Quick answer: Your pelvic floor is a group of muscles stretching from your pubic bone to your tailbone. These muscles support your bladder, bowel, and uterus (if you have one), and they play a direct role in sexual function, arousal, orgasm intensity, and comfort during penetration. A weak pelvic floor can reduce orgasm strength and contribute to incontinence. A hypertonic (too-tight) pelvic floor can cause pain during sex. Both are common, and both are treatable with the right approach.
You've been told to do your Kegels. Probably by a magazine, a midwife, or an Instagram infographic with a pastel background. What you probably weren't told is why, how to tell if you're actually doing them right, what happens if your pelvic floor is too tight rather than too weak, or the fact that these muscles are directly involved in how your orgasms feel. This is the guide that fills in the blanks.
What the pelvic floor actually is
The pelvic floor is a hammock-shaped group of muscles and connective tissue that sits at the base of your pelvis. It stretches from the pubic bone at the front to the coccyx (tailbone) at the back, and between the sit bones on either side. These muscles have three openings passing through them: the urethra, the vagina (in people who have one), and the anus.
Think of the pelvic floor as a trampoline. When it's working properly, it has bounce, it contracts and relaxes in response to what your body needs. When it's too weak, it sags (leading to leaking and reduced sensation). When it's too tight, it doesn't give (leading to pain and difficulty with penetration). The goal isn't maximum strength. It's function, muscles that can contract, relax, and coordinate.
How the pelvic floor affects sex
Orgasm
During orgasm, the pelvic floor muscles contract rhythmically, those involuntary pulses you feel are your pelvic floor. Stronger, more coordinated pelvic floor muscles can produce stronger, more intense orgasmic contractions. A 2010 study in The Journal of Sexual Medicine found that women with stronger pelvic floor muscles reported higher sexual satisfaction scores and more intense orgasms.
This is the main reason people are told to "do their Kegels", strengthening these muscles can genuinely enhance orgasm quality. But strength alone isn't the full picture.
Arousal
The pelvic floor muscles help regulate blood flow to the genital area. When you become aroused, increased blood flow causes engorgement of the clitoris and surrounding tissue (similar to an erection). Pelvic floor muscles that contract and relax properly support this blood flow. A dysfunctional pelvic floor, too weak or too tight, can impair this process, reducing arousal sensation.
Penetration comfort
For penetration to be comfortable, the pelvic floor needs to relax and lengthen. If the muscles are chronically tight (hypertonic), penetration can feel painful, burning, or impossible. This is one of the most common causes of pain during sex that people don't know about, they assume the pain is about anatomy or arousal, when it's actually a muscular issue.
If penetration hurts, that's not something to push through. It's worth reading our when sex hurts guide and seeing a pelvic floor physio who can assess whether your pelvic floor is contributing.
Signs your pelvic floor might need attention
-
Leaking urine when you cough, sneeze, laugh, or exercise (stress incontinence)
-
Feeling like you can't fully empty your bladder
-
Pain during or after penetrative sex
-
Difficulty reaching orgasm, or weaker orgasms than you used to have
-
A feeling of heaviness or dragging in the pelvic area
-
Urgently needing to pee with little warning
-
Pain in the vulva, perineum, or lower abdomen that doesn't have an obvious cause
Some of these suggest weakness; some suggest tightness. A pelvic floor assessment from a qualified professional can tell you which, and that distinction matters because the treatment is different.
Pelvic floor exercises (and when not to do them)
Kegels: the basics
A Kegel is a contraction of the pelvic floor muscles, the same muscles you'd use to stop the flow of urine midstream. (Don't actually do that regularly as an exercise, though, it can interfere with bladder function. Just use it once to identify the right muscles.)
To do a Kegel: squeeze those muscles, hold for 3-5 seconds, then fully relax for 3-5 seconds. The relaxation is just as important as the contraction. Repeat 10 times, three times a day. Build up to 10-second holds as you get stronger.
Common mistakes: holding your breath (keep breathing normally), squeezing your buttocks or thighs instead of the pelvic floor (only the internal muscles should be working), and not relaxing fully between contractions (partial relaxation trains the muscles to stay partially tense).
When Kegels are the wrong answer
If your pelvic floor is already too tight (hypertonic), Kegels can make things worse. Symptoms of a hypertonic pelvic floor include pain during penetration, burning sensations, difficulty starting urination, and pelvic pain. In this case, what you need is relaxation and lengthening work, stretches, breathing exercises, and often professional help from a pelvic floor physio. Strengthening an already over-tensed muscle is counterproductive.
This is why the blanket advice to "just do your Kegels" is incomplete. Without knowing whether your pelvic floor is weak, tight, or a combination, you could be doing the wrong exercise entirely.
Pelvic floor tools
Kegel trainers and pelvic floor exercisers can help with strengthening by providing something to squeeze against, which makes it easier to isolate the right muscles. Weighted kegel balls are another option, you insert them and your pelvic floor works to keep them in place, providing a passive workout.
Vibrators can also be useful for pelvic floor work, gentle vibration can help tense muscles relax, and using a vibrator during pelvic floor exercises can increase body awareness and blood flow. The VUSH collection includes options suited to this.
Life events that affect the pelvic floor
Pregnancy and birth
Pregnancy puts significant load on the pelvic floor from the weight of the growing uterus. Vaginal birth stretches the muscles further, and sometimes causes tears or nerve damage. Postpartum pelvic floor rehabilitation is standard in many countries but woefully underprescribed in others. If you've given birth and are experiencing any pelvic floor symptoms, a postnatal assessment is worth pursuing.
Menopause
Declining oestrogen thins the vaginal tissue and reduces the elasticity of pelvic floor muscles. This can contribute to incontinence, reduced sexual sensation, and discomfort during sex. Pelvic floor exercises, topical oestrogen (with medical guidance), and appropriate lubrication all help. More in our sex during menopause guide.
Chronic constipation and straining
Regularly straining on the toilet puts downward pressure on the pelvic floor, which weakens it over time. If you're chronically constipated, addressing that (through diet, hydration, or medical advice) also protects your pelvic floor.
High-impact exercise
Running, jumping, and heavy lifting can stress the pelvic floor, especially if the muscles are already weak. This doesn't mean you should avoid exercise, it means you should include pelvic floor exercises in your routine alongside everything else. Athletes experience pelvic floor issues more often than most people think.
The connection between stress and the pelvic floor
Stress doesn't just live in your head, it lives in your muscles. When you're chronically stressed, you tense muscles without noticing. Jaw clenching, shoulder hunching, and pelvic floor gripping are all part of the same pattern. People who carry stress in their body often develop hypertonic pelvic floors without any obvious physical trigger like childbirth or surgery.
If you sit at a desk all day, clench through stressful meetings, or hold tension during exercise, your pelvic floor may be chronically tight. Learning to consciously relax it, through breathing, stretches, and body awareness, is as important as strengthening it. Diaphragmatic breathing (belly breathing) is one of the most effective ways to release pelvic floor tension, because the pelvic floor and diaphragm move together.
When to see a professional
If pelvic floor symptoms are affecting your daily life, sex life, or mental health, see a pelvic floor physiotherapist. These are specialised professionals trained to assess and treat pelvic floor dysfunction through internal and external examination, manual therapy, exercise prescription, and biofeedback.
In Australia, you can ask your GP for a referral or find a pelvic floor physio directly. Initial assessments typically include a detailed history, external and (with consent) internal examination, and a personalised treatment plan.
Pelvic floor dysfunction is not something you have to live with. It responds well to treatment in most cases, and the earlier you address it, the better the outcomes.

FAQs
How long does it take for pelvic floor exercises to make a difference?
Most people notice improvement in 4-6 weeks of consistent daily exercises. Significant changes, in orgasm quality, incontinence, or pain, usually take 3-6 months. Consistency matters more than intensity.
Can men have pelvic floor issues?
Yes. People with penises have pelvic floors too, and they can be too weak or too tight. Pelvic floor dysfunction in men can contribute to erectile issues, premature ejaculation, chronic pelvic pain, and urinary problems. The exercises and treatments are similar.
Is it normal to leak during exercise?
Common, yes. Normal, in the sense that it should be accepted and not treated, no. Exercise-related incontinence is a sign that the pelvic floor isn't coping with the load. Pelvic floor strengthening, technique modification, and possibly professional assessment can resolve it.
Can I overtrain my pelvic floor?
Technically yes. Overdoing Kegels without adequate relaxation can lead to hypertonic muscles, which cause their own problems (pain, difficulty with penetration, urinary issues). Follow the exercise guidelines and always include the relaxation phase. If symptoms worsen, stop and see a professional.
Will a vibrator help my pelvic floor?
It can, indirectly. Vibration increases blood flow to the pelvic area, which supports tissue health. Using a vibrator can also improve body awareness, many people become more attuned to their pelvic floor muscles through sexual arousal and orgasm. It's not a substitute for targeted exercises, but it's a complementary addition.
