The pelvic floor sits directly in the middle of sexual function, which means it can affect sex in two almost opposite ways, and the fix depends entirely on which one applies. A pelvic floor that's weak can mean less sensation, less control, and a lower ability to reach orgasm; a pelvic floor that's too tight can mean pain during penetration, difficulty relaxing, or discomfort that shows up after sex rather than during it. Both get talked about as "pelvic floor problems." They need close to opposite solutions.
If the pattern is weakness (sensation feels muted, orgasm takes longer or feels less intense, or there's a sense of looseness), pelvic floor strengthening is a reasonable thing to try. Kegel exercises build the same muscle that contracts during orgasm; consistent practice over weeks, not days, is what gives them a fair test. What Kegel exercises actually do.
If the pattern is pain (sex that hurts on entry, a feeling of tightness or bracing, discomfort that lingers afterward), strengthening is the wrong direction, and more squeezing can make it worse. That's a tightness problem, and it calls for relaxation-focused work and, ideally, a pelvic floor specialist. Tight or weak: how to tell.
Kegelia is built for the first case, not the second: it shows the lift and the release, which helps when the goal is more strength and control, not when the goal is release. If pain is the symptom, start with the assessment, not the app.
What the pelvic floor does during sex
During arousal the pelvic floor needs to be able to relax so that penetration is comfortable, and during orgasm the same muscles contract in quick, rhythmic pulses. That's why both directions matter: a floor that can't contract well may make sensation and orgasm feel muted, and a floor that can't let go may make sex painful. Good function is less about raw strength than about being able to do both on demand.
What the evidence says about strengthening and sex
Reviews of pelvic floor training in women have found better scores for arousal, orgasm and satisfaction, but with very low certainty, because the studies were small and varied. It's a reasonable thing to try when the pattern is weakness, especially after childbirth, but it isn't a guaranteed fix, and no app or exercise can promise a particular result.
After birth and around menopause
After a baby, wait until you feel ready and your provider has checked any tear or scar; sex can feel different for months, and gentle pelvic floor work often helps sensation come back. Around menopause, falling estrogen can make vaginal tissue drier and thinner, which can cause pain that has nothing to do with muscle strength. Lubricants and moisturizers help many people, and vaginal estrogen is an option to discuss with a clinician.
Who to talk to
If sex hurts, a gynecologist or primary care doctor can rule out causes such as infection, skin conditions or endometriosis, and a pelvic floor physiotherapist can assess whether the muscles are too tight, too weak, or both. It's a common reason people see one, and you don't need to push through pain while you wait.
