two ultrasound studies of women who exercised their vaginal muscles did find that their muscles were thicker and stronger after pelvic floor muscle training. among women with urine leakage their thinner muscles became the thickness of healthy women's pelvic floor muscles. additionally they had less urine leakage -- whether the problem was from stress or urge types of incontinence. the use of vaginal cones and/or kegel exercises to increase muscle strength were both found to improve tone and decrease urine loss. while some of these studies did not measure vaginal tightness per se when muscle bulk is increased a woman can voluntarily contract those muscles to make the vaginal opening tighter.
will exercising the vaginal muscles make my vagina tighter?
