For example, if a woman does tons of kegels and then has sex, will her man notice a difference in tightness without her actually having to manually "squeeze" her vaginal muscles? Or are the purpose of kegels just to enable the woman to squeeze stronger? Will her vagina become loose again once she stops squeezing?
Re: Do kegels actually tighten the vaginal muscles or do they just allow the woman to squeeze tighter?
Kegal exercises strengthen the pelvic, not vaginal, muscles.
