The pelvic floor can fail in two opposite directions and both affect sex. Muscles that are too tense produce pain with penetration, difficulty with orgasm, and a sense of never releasing; muscles that are too weak produce reduced sensation, leakage, and prolapse symptoms that make sex feel unsafe. Tension is by far the more commonly missed of the two, partly because the standard advice is to do more pelvic floor exercises, which makes an overactive floor worse.

New or worsening leakage of urine or stool needs assessment rather than management at home.
A feeling of something coming down, or a visible bulge, needs examination.
What the condition itself tends to do
Editorial categories, not percentages, and never a prediction about you. Each links to the fuller picture of that change.
Burning, tearing, or aching pain with penetration. Pain is never a symptom to work around with a product — it is the one entry on this list that always deserves assessment.
Arousal works but orgasm does not arrive. When this starts within weeks of a new medicine and had never happened before, the timing itself is information.
The body responds less, or much more slowly, even when the interest is there. Blood flow, nerve signalling, and hormone levels all feed this, and medicines can act on any of the three.
Wanting sex less often, or losing the spontaneous interest that used to arrive on its own. This is the effect people most often assume is psychological and most often is not only psychological.
Condition or treatment?
There is no medicine for this either. Specialist pelvic-floor physiotherapy is the treatment, and which direction the exercises go in depends entirely on which way the muscles are failing — which is exactly why assessment matters before exercises.
For almost every condition on this site, the condition and the medicines that treat it both affect sex — by different mechanisms, on different timescales, and with different answers. Being able to say which half you are asking about is the single most useful thing you can bring to an appointment, and it is the thing patients are least often given.
No medicine class on this site is a standard treatment for this, which is itself useful to know — if a treatment is being suggested, it is worth asking what it is expected to do.
What helps
Ask for an assessment before doing exercises, because strengthening an already-tense floor makes symptoms worse.
Breathing and downward-release work, not clenching, is what an overactive floor needs.
Plenty of lubricant reduces the friction that triggers guarding in the first place.

Common questions
How does pelvic floor dysfunction affect sex?
The pelvic floor can fail in two opposite directions and both affect sex. Muscles that are too tense produce pain with penetration, difficulty with orgasm, and a sense of never releasing; muscles that are too weak produce reduced sensation, leakage, and prolapse symptoms that make sex feel unsafe. Tension is by far the more commonly missed of the two, partly because the standard advice is to do more pelvic floor exercises, which makes an overactive floor worse.
What are the most common sexual effects of pelvic floor dysfunction?
The effects reported most often are pain during penetration. Reported does not mean inevitable — the picture varies a great deal between people, and most people have more than one thing contributing at once.
Is it pelvic floor dysfunction or the treatment for it?
There is no medicine for this either. Specialist pelvic-floor physiotherapy is the treatment, and which direction the exercises go in depends entirely on which way the muscles are failing — which is exactly why assessment matters before exercises. Timing is the most useful clue you have: an effect that appeared within weeks of starting or changing a treatment points at the treatment, while one that predates it points at the condition. Never stop, pause, or change a prescribed treatment to find out — take the timeline to the person who prescribed it.
What helps with the sexual effects of pelvic floor dysfunction?
Ask for an assessment before doing exercises, because strengthening an already-tense floor makes symptoms worse. Breathing and downward-release work, not clenching, is what an overactive floor needs. Plenty of lubricant reduces the friction that triggers guarding in the first place.
When should I raise this with a clinician about pelvic floor dysfunction?
Sooner than most people do, and specifically without waiting: New or worsening leakage of urine or stool needs assessment rather than management at home.
Educational information about what a diagnosed condition tends to do — not a diagnosis, not a way to work out whether you have something, and not advice about your treatment. Conditions on this page overlap, and most people with a long-term condition have more than one thing affecting them at once. Nothing here can examine you or run a test. Pain, bleeding, or a new and unexplained symptom always deserves assessment.
