Does Sex Only Hurt in Certain Positions?
That Clue Points to Pain During Sex Causes Most Couples Never Check.
Short answer: If sex only hurts in certain positions, two common causes of pain during sex are worth checking first: the angle of her hips and how hard her joints work to hold her there. The WildNightX Pillow keeps a steady 27° in 15+ positions, but see a doctor if pain is sharp, new, or in every position.
What spine researchers learned about positions and pain
"What we know now is that sex positions that are suitable for one type of back pain are not appropriate for another kind of pain"
Natalie Sidorkewicz, a PhD candidate in Waterloo's Faculty of Applied Health Sciences who led the study, speaking to University of Waterloo News
Friend, Does This Sound Familiar?
Lying face to face is fine. Slow. Close. Easy.
Then you try her favorite. The one that used to be the one. A minute in, she shifts. Then she winces. "It's fine," she says, and you both know it isn't.
The next morning she's rubbing her hip. So that position quietly goes on the "maybe never" list. Then another one does.
One person wrote in a pillow review that "our favorite position was wreaking havoc on my hips." Plenty of couples know exactly what that means.
Professor Stuart McGill, of Waterloo's Faculty of Applied Health Sciences, has seen where this road leads: "Many couples will remain celibate because one night of love-making can lead to months of back agony."
But What If the Position Isn't the Real Problem?
Here's the clue most couples miss. If it only hurts in some positions, the pain is following something that changes when you switch.
Two things change every time: the angle of her hips, and how much work her hips, back, and knees do to hold her there.
(If pain is sharp, new, or shows up in every position, that's a doctor's visit, not a pillow problem.)
Position Clue #1: Face Down or Kneeling
In these positions, her knees and lower back carry her weight the whole time. On a soft mattress, her hips also tip to one side, so the angle keeps changing.
That's why it can feel good at first and ache a few minutes later. Her joints are working, not resting.
What helps: lying face down with a firm wedge under her hips and belly. Her body rests on the foam instead of on her knees.
Position Clue #2: At the Edge of the Bed
The edge of the bed is almost never the right height. One of you crouches. She slides toward the edge and holds herself in place with her legs.
A height mismatch forces the angle, and a body holding itself still gets tense fast.
What helps: a firm wedge at the edge of the mattress. It raises her hips to a better height and keeps her from sliding.
Position Clue #3: Lying on Her Side
Side by side sounds like the gentle choice. But on a flat bed, her lower hip sinks while her top hip twists to keep things lined up.
That twist is exactly what shows up as a sore hip the next day.
What helps: a wedge under her lower hip. It levels her hips, so nothing has to twist.
Pain During Sex? Check the Hidden Weak Spot in Every Position
Notice the pattern? In each clue, the same two things go wrong:
- The Angle Drifts: A mattress sinks, bed pillows squash, and her hips end up at a tilt that strains instead of supports.
- Her Joints Do the Holding: Hips, lower back, and knees work the whole time. Working joints get sore, and sore joints make the next try tense.
You've Been Trapped: Her Favorite Hurts → You Skip It → Fewer Positions → Less Fun → She Starts to Think Her Body Is the Problem.
But What If One Pillow Worked in Every Position?
Imagine one firm cushion that sets a steady angle in any position you choose. Under her hips when she lies back. Under her hips and belly when she lies face down. At the edge of the bed. On her side.
No new pile to build each time. Same support, every position.
Meet the WildNightX Pillow
The WildNightX Pillow gives her hips, back, and knees a break, whichever position you pick:
- ✅ Fixed 27° Angle: The tilt doesn't drift, so a comfortable position stays comfortable.
- ✅ Takes the Load Off Her Joints: The curved, chair-like shape carries her weight instead of her knees and lower back.
- ✅ Works in 15+ Positions: Lying back, face down, side by side, edge of the bed, and more.
- ✅ 60 kg/m³ Memory Foam, Rated for 260+ lbs: Firm enough that it doesn't sink halfway through.
- ✅ Silicone Grip Base: Stays in place on sheets, mattresses, and floors.
- ✅ Linen Cover That Zips Off: Soft, breathable, and machine washable.
It's Not Magic, It's One Pillow Instead of a Pile: The WildNightX doesn't treat pain. It just keeps the angle steady and takes the weight off her joints, in whatever position feels right.
‘Will It Work in OUR Favorite Position?’ We Get It.
Every couple is different, and so is every body. That's why the pillow works in many positions instead of just one.
And to be honest: it isn't medicine. If pain keeps coming back no matter what you try, see a doctor. But if the pain follows certain positions, steady support is a smart thing to try.
Here's what couples who own this pillow say:
"It works great! I love how it put my hips at different angle!"
Sarah H., July 2026
"have had difficulty in most intimate 'Connections'; but ever since we use the [pillow], our Sessions are a more Comfortable!"
Brad B., September 2026
"Using the pillow makes the angle feel natural"
Vince M., July 2026
Your Turn to Bring Her Favorite Back
Stop crossing positions off the list. Stop waking up to a sore hip and a quiet promise to skip that one next time.
Imagine: Trying her favorite again, with her hips held steady and her joints at rest. Laughing instead of wincing. Waking up without the ache.
This is the WildNightX possibility.

Pain During Sex Causes FAQ
Why is sex painful?
There are many reasons, and some are medical, so see a doctor if pain is sharp, new, or shows up in every position. If it only hurts in some positions, the pain may be following the angle of her hips and the work her joints do.
What causes pain during sex that couples often miss?
Two things that change every time you switch positions: the angle of her hips, and how much her hips, back, and knees work to hold her there. A mattress that sinks and pillows that squash make both worse.
How can a wedge help in different positions?
Face down, it goes under her hips and belly so her knees can rest. At the edge of the bed, it raises her hips to a better height. On her side, it goes under her lower hip so nothing has to twist.
Will a pillow treat the pain?
No. It isn't medicine. The WildNightX keeps the angle steady and takes the weight off her joints. If pain keeps coming back no matter what you try, see a doctor.
Why Cross Off Another Position?
When pain only shows up in certain positions, the angle and the support are worth checking first. Give her a steady 27° base and let her joints rest.
