Most sex advice assumes a body that does what it’s told. Bend here, hold this, support your weight on that joint for as long as it takes. For those with hypermobility, dysautonomia, fibromyalgia, or other chronic pain conditions, that whole framework is the wrong starting point. The body has different rules, and the positions and mechanics that work follow from understanding those rules, not from working around them.
If you’ve come over from the main guide, this is the piece on what actually works when joints subluxate, when standing too long drops your blood pressure, when one wrong angle locks your back for a week. We’ve pulled this together from two sources: the community knowledge sitting across the chronic illness subreddits (r/ehlersdanlos, r/Hypermobility, r/POTS, r/cfs, r/ChronicPain, r/ankylosingspondylitis, and others) and the biomechanics literature on hip stability and joint loading in hypermobile populations.
This isn’t a list of “best positions for chronic pain” because that list doesn’t exist. What works depends on which joints are unstable, which directions of load you can tolerate, what your fatigue baseline is on a given day. What does exist is a set of principles that hold across conditions, and a set of community tested adjustments that turn up again and again across the threads. That’s what this covers.
The principle that makes everything else make sense
The single most useful idea, drawn from years of forum threads and consistent with what the biomechanics literature shows, is this: when it comes to positioning with a hypermobile or chronically painful body, the goal is to reduce range of motion, not increase it. Sex advice culture has spent decades telling people to push for flexibility, get into the more demanding positions, prove their athleticism. That’s the opposite of what’s needed here.
Hypermobile joints already have too much range. The connective tissue holding them in place is less restrictive than it should be, the muscles supporting them have to work harder to maintain stability, and any position that pushes a joint to the end of its available range is asking the surrounding tissue to take a load it’s not well designed for. The hip is the most commonly affected joint in this context. Hip instability in EDS and hypermobility populations is genuinely multi-directional, with anterior instability (combined extension and external rotation) often the most cited trigger in the clinical literature, but the position that comes up most often as a problem during sex is the one that asks the hip to abduct (open outward) past where the bony anatomy provides containment.
There’s a clinical paper from Larson et al. that’s worth knowing about [1]. It describes a series of people with EDS and extreme soft tissue hip instability who underwent arthroscopic capsular plication because the standard ligamentous containment of the hip wasn’t doing its job. The conclusion isn’t that everyone with hypermobility needs surgery. The conclusion is that for some people, the soft tissue containment of the hip is genuinely insufficient, and the positions that ask the joint to hold itself against external force at end range are the ones that will cause problems.
So the principle: keep joints in their stable mid range, support them externally where possible, and avoid asking the soft tissue to hold the joint in place against a load. Almost every position adjustment that comes up across the community threads is an application of this single idea.
The positions that come up most often, and why they work
Across the threads, certain positions show up repeatedly across very different conditions. The reason they work isn’t mysterious. They reduce joint range, they distribute weight onto the bed or floor rather than onto joints, and they let the partner with pain stop holding themselves up.
Spooning and side-lying variations. This is the most-cited position across r/Hypermobility, r/ehlersdanlos, r/ChronicPain, and r/POTS. Both partners lie on their sides, the receiving partner facing away or in a modified angle. The key adjustment for hypermobility specifically is to keep the top leg forward rather than letting it splay sideways. As one r/Hypermobility user put it: “If you bring a leg forward it doesn’t need to spread out sideways,” which keeps the hip from being driven into abduction at end range.
Side-lying also takes the orthostatic load off, which matters significantly for POTS and dysautonomia. There’s no demand on the cardiovascular system to maintain pressure against gravity. For ME/CFS and severe fatigue, it’s the lowest energy cost position by a margin.
Prone (flat on stomach) with pillows under the hips. Lying flat on the stomach with the hips slightly elevated, partner approaching from behind, gets recommended consistently for hip pain. The hip is held in a narrow range, the weight is on the mattress not the joint, and there’s no need to hold any posture. One r/ehlersdanlos user described this as “the most comfortable and least stressful position, and it definitely works”. The pelvis can be supported by a wedge or pile of pillows to find the angle that doesn’t compress the lower back.
Modified missionary with elevated hips and bent knees. Lying on the back is fine. The problem with traditional missionary is the partner being asked to hold their legs wide open, which forces hip abduction at end range. The modification is straightforward: pillows or a wedge under the hips, knees bent rather than legs straight and spread, and feet flat on the bed or supported. This keeps the hip in a more neutral position and removes the muscular work of holding the legs open.
Cowgirl with a bolster, but selectively. Being on top gets recommended specifically for hEDS because the person with hypermobility controls the range of motion and can stop a partner from inadvertently pushing the hip past where it should go. The same position gets actively warned against for POTS, dysautonomia, ME/CFS, and fibromyalgia, because the orthostatic and muscular demand is high. Same position, opposite recommendation depending on which condition is the bigger problem. The pillow or wedge under the bottom partner’s hips makes the angle more workable and removes some of the work for the partner on top.
Edge of the bed positioning. Standing or kneeling at the edge of the bed with the receiving partner’s hips supported on the mattress. Gets recommended specifically for AS and lower back issues, because the spine doesn’t have to do the work of holding the body up. Knee pads (gardening knee pads turn up across threads) make this workable for the standing partner if they have knee issues.
Side-lying with the receiver leaning over the bed. A specific adjustment for lower back problems where spinal extension is the problem. Reduces extension load, keeps the spine in a more neutral position.
What runs through all of these is the same principle. Joints held in their middle range, body weight on the bed rather than on the joint, the partner with the painful body not having to hold themselves up.
The positions and mechanics that consistently cause problems
The flip side. When it comes to mechanics that consistently get people hurt, these show up across the threads as things that cause injuries, dislocations, or flares.
Missionary with legs spread wide. The single most common trigger for hip subluxation in the hEDS threads. Pulling the knees up toward the chest while the legs are spread wide drives the hip joint into the position where the soft tissue containment is at its weakest, and for some people the hip slides out at exactly that point. The fix isn’t subtle. Don’t put the legs wide. Bend the knees instead. Keep the hips in a workable range.
Being the active partner on top, in conditions with cardiovascular or fatigue load. The orthostatic demand is significant, the core demand is significant, and the autonomic system tends to struggle. For POTS specifically, being on top frequently triggers presyncope (the feeling of being about to faint) and post-activity crashes. “Being on top is especially hard, so I don’t do it often,” wrote one r/POTS user.
Sustained positions held for long periods. Across the threads, the recommendation to switch positions every few minutes turns up repeatedly. The reasoning is that prolonged static loading of a joint causes problems even at otherwise tolerable angles. The connective tissue gets fatigued, the muscles supporting it tire, and what was fine for two minutes becomes a problem at ten.
Partner uninstructed. The threads consistently warn against expecting a partner to know what is and isn’t safe. The specific thing that causes hip subluxation, partner pulling someone’s knees toward their chest, is the kind of thing a partner does instinctively, and it has to be specifically named as a no. Tell partners: no pulling the knees up. If the receiving partner needs to keep their legs together when transitioning between positions, that needs to be said. The injury threads are full of people who had a partner do something they didn’t know was a problem.
Over-widening because it feels normal. An r/Hypermobility user named this directly: “Are you widening more than necessary because it feels natural or normal?”. For people whose hips can go past where most can, the available range isn’t the same as the safe range. Just because the joint will open that far doesn’t mean it should under load.
What the biomechanics literature actually says about this
The community knowledge sits on top of a real biomechanical picture, and it’s worth grounding the principles above in what the published research shows. This isn’t the section where research saves the day. It’s the section where research backs up what people already worked out by trial and error.
A study by Hulburt et al. on adolescents with juvenile fibromyalgia, with and without joint hypermobility, looked at landing and jumping biomechanics [2]. What they found is relevant beyond the specific task. Both fibromyalgia groups showed altered lower extremity biomechanics compared to controls: increased hip and ankle range, reduced knee and ankle kinetic output, and roughly 2.5 times greater knee internal rotation during landing. The authors noted that hypermobility was associated with directionally more inefficiencies, but it did not statistically differentiate the hypermobile and non-hypermobile fibromyalgia groups, with both showing broadly similar patterns of altered biomechanics compared to controls. The interpretation the authors offered was that the altered biomechanics may reflect an attempt to avoid pain. In other words, the body is already compensating, and any position that asks the joint to take load at end range is asking it to do something it’s already showing it would prefer not to do.
A separate gait study by Jeong et al. on children with hypermobility spectrum disorder looked at lower extremity coordination during walking [3]. The honest reporting here is that the study’s specific findings were null: inter-joint coupling angles, patterns and variability weren’t significantly different from controls during simple walking, and the authors themselves concluded that this particular area might not be a promising one for further research or intervention in paediatric HSD. The broader claim that pain, proprioception deficits, and joint instability are core features of hypermobility conditions, and that the body knows where it is less reliably, is well supported in the wider hypermobility literature rather than by this specific paper’s results.
Put together with the surgical literature on EDS hip instability [1], the picture is reasonably clear. The hip in hypermobility is often genuinely unstable, the body is already compensating, and the sexual positions that work are the ones that don’t push the joint into the position where its instability becomes a problem.
Props, supports, and what actually helps
Pillows do most of the work here. Specifically:
Wedge pillows. The most-cited prop across every chronic illness community. Drive Medical wedge (around thirty dollars), cheaper post-surgery wedges (under fifteen), or the Liberator wedges if you want the sex-specific ones (more expensive, broadly similar function). One r/ehlersdanlos user noted: “The materials are the same, but the cost is only a fraction”. The expensive ones are not meaningfully better than the cheap ones.
Body pillows and C-shaped pregnancy pillows. Provide multi-point joint support across positions. The C-shape in particular handles head, torso, knee, and ankle support in one prop.
KT tape and kinesiology tape. Comes up specifically for joint stability. Applied around the SI joint before sex for those whose lower back instability is the issue, applied around the hips for those whose hips slide. The reason it gets used over a full brace is exactly what one r/disability user noted: “KT tape makes for good bracing while still feeling naked! My full knee braces just will never feel sexy to me”. We’ve covered KT tape application elsewhere on the site for those who want the specifics.
Compression wear, wrist braces, soft knee supports. Some people keep these on during sex when the specific joint is the most vulnerable point. Aesthetic concerns are real, but for some, the trade off is worth it.
Sex swings, slings, and rope work. Comes up across the threads as a way to remove physical load by letting an external support hold the body in position. The investment is more significant, and they need research and setup, but for some people they’re the difference between intimacy being workable and not. Shibari (Japanese rope bondage) gets specifically mentioned in r/ehlersdanlos threads as something that provides both external joint support and sensory input. Not for everyone, but worth knowing about.
Gardening knee pads. A practical and unromantic recommendation for positions that involve kneeling on a hard surface or on a bed for too long. The threads are full of people who learned this the hard way.
Foam rollers and tools nearby. Several people in the threads keep a foam roller, hip flexor stretch, or other reset tool near the bed for after the fact. Hips that lock up post-activity respond well to having something on hand to address them. One r/Hypermobility user wrote: “Lol it’d be 2 am and I’d be getting out my foam roller”. Mundane, but it makes a difference.
The specific moves that prevent hip subluxation
For the hEDS readers specifically, because this is where most of the injury threads concentrate.
Keep the hips on the mattress. Several r/ehlersdanlos threads identify the trigger for hip sliding as the moment the hips come up off the bed during activity. Keeping the pelvis grounded on the mattress, rather than lifting it, is the single most consistent recommendation.
Bring legs together before transitioning. When repositioning, the legs need to come together slowly and deliberately before either leg moves independently. “If I don’t bring them together before moving one, usually the right, it slides partially out of the socket”. This is a piece of information the partner needs.
Cuffs or restraints as positional aids. Worth flagging because it comes up in the threads and the framing is non-obvious. One r/ehlersdanlos user uses wrist and ankle cuffs not for kink reasons but as a way to keep limbs in position without having to hold the posture: “The cuffs allow me to fully relax without having to maintain any particular posture”. Functional positioning tool, not necessarily a kink statement.
Post-activity reset. Several threads describe specific manoeuvres to reset hips that have shifted during sex. One user uses a “shake-kick” motion to reset; others use foam rollers, hip flexor stretches, or partner-assisted realignment. None of this is medical advice on what your specific reset should look like. The point is that having a known reset, rather than panicking when the hip moves, makes a meaningful difference.
The strength work that pays off here
This is the part where the biomechanics and the community knowledge converge on the same thing. The hEDS threads consistently point to muscle-based stability work as the thing that translates directly to better in-session stability. The most-cited exercise is the glute bridge. One r/Hypermobility user: “On days when I don’t do anything else, I make sure to complete at least 20 glute bridges. This translates directly to better in-session stability”.
The same threads consistently warn against stretching as a strategy for hypermobile joint pain. The intuition that you stretch a sore joint to make it feel better turns out to be wrong for hypermobility, and several users in the community have figured this out the hard way. “Increasing strength and building muscle will stabilize things better than stretching. I’ve had hip joint pain for years and those stretches haven’t helped; they sometimes worsen the pain”.
The mechanism makes sense. If the joint already has too much range, stretching adds to the problem. What it needs is the muscular support that lets it stay where it should be. Glute bridges, hip thrusts, side lying clams, and similar lower-load hip strengthening exercises do exactly that. The full programme for this isn’t this blog’s job, but the principle is worth naming: when it comes to translating off-bed work into on-bed function, building muscular stability around the hip is the highest yield place to put your time.
POTS, dysautonomia, and the orthostatic problem
A separate set of considerations for POTS, dysautonomia, MCAS, and other conditions where the autonomic nervous system is the issue rather than the joints. When it comes to these conditions, the principles change.
The basic problem is that anything which raises heart rate, drops blood pressure on position change, or shifts blood volume away from the brain triggers the symptoms. Sex does all three. Standing positions, being on top, sudden position changes, and rapid arousal can all set off presyncope or syncope. Several r/POTS users describe the experience of nearly fainting at orgasm as something they had to learn to plan around.
The positional adjustments are: stay horizontal, stay in side-lying or supine, avoid being on top, avoid standing positions, and avoid rapid position changes. Most of these overlap with the joint-protective recommendations, which is convenient when both apply.
Pre-session adjustments come up across the threads: salt loading, electrolyte fluid intake (LMNT, salt water, electrolyte tabs) thirty to sixty minutes before, compression garments staying on during. For people on beta blockers, taking the scheduled dose before rather than after is often a useful adjustment. None of this is medical advice on what your specific regimen should look like, but it’s the pattern of adjustments people have worked out themselves.
One last thing about pain during, and what to do
When it comes to in-the-moment pain, the rule is simple. If a position causes a sharp pain, a click, or a sense that something has moved, the move is to stop. Not finish the position and address it after. Stop, slowly bring the body to neutral, and assess. The threads are full of people who tried to “push through” a position that was clearly causing damage and ended up with weeks of flare from what could have been a brief pause.
If pain during intercourse is happening consistently, and it’s not a positional issue you can solve, then it’s worth reading the pelvic floor pain piece which goes into the pelvic floor side of this in more detail. Pain during sex isn’t a thing to grit your teeth through. It’s diagnostic information that tells you something needs to change.
And it’s worth saying explicitly: there is no version of this where you owe your partner intercourse. Positions are a tool to make intimacy work when it can. They’re not a checklist to push through. If the body’s saying no on a given day, the body’s saying no. The intimacy work doesn’t disappear just because penetrative sex is off the table.
Where to go from here
The next steps depend on which bit was relevant. If joint instability is the issue, the glute strengthening work and the wedge pillow setup are the highest-yield places to start. If pain during intercourse is the issue, the pelvic floor piece covers what’s actually involved in addressing it. If the energy and autonomic load is the issue, the pacing piece on the hub covers how to plan around that.
And if there’s a partner involved, the communication piece covers how to have the conversation about adjustments without it turning into a clinical briefing. The positions only work if you’ve actually told the partner what you need.
If you want help getting the underlying strength and stability work in place, that’s what we do at The Fibro Guy. The programme covers the kind of muscular stability work that translates into joints that hold themselves in place. The kind of work that makes positioning easier, not because you’ve memorised a list of safe positions, but because the body is in a better state to handle the demands.
