Home → Glossary → Pelvic Floor

The pelvic floor is a hammock-shaped group of muscles stretching from the pubic bone to the tailbone. These muscles support the bladder, rectum, and uterus (or prostate). They contract during orgasm and play a direct role in orgasm intensity. Stronger pelvic floor muscles correlate with stronger, longer orgasms for all genders. Kegel exercises (squeeze and hold, then release) are the classic strengthening method. Weighted kegel balls provide passive resistance training. For people with penises, pelvic floor strength affects erection quality and ejaculation control. Weakness (from aging, childbirth, surgery, or chronic straining) can cause incontinence and reduced sexual sensation. If basic exercises don't help, a pelvic floor physical therapist can provide targeted rehabilitation.
