Child bearing does indeed loosen the muscles of the vagina. The
techniques we divulge to you will easily and quickly give you strength
over what you had as a virgin, and control of the most seasoned
courtesans.”
From a company that sells a book on how to exercise the vagina

“My New Year resolution will be to exercise my vaginal muscles so
they really can squeeze the life out of the guys.”
Editor of an erotic magazine

With some women, the man will experience a wonderful secret
during her orgasm. Don’t any of you women who know about
this let the secret out.
I will not only let the secret out but tell men that women who do
their Kegels can constrict their vaginal muscles like that voluntarily,
at least some of the time, and that even trying to do it when it doesn’t
quite come up to that level is pleasurable.”
Anonymous woman (from a discussion on use-net)

“Some of you may have the pleasure, as I do, of having a wife that does
Kegel exercises to tighten up the vaginal muscles. Very nice feeling during
intercourse.”
Anonymous man, from a news group

“My girl friend plays with her muscles and she says it feels better when the
fit is tight.”
Anonymous man

“The first time I made love, after the vaginal exercise course, and used
my love-muscle, was with my workmate Andrew. It was fantastic.
Waves of pleasure rinsed through my body and I got goose flesh all over.
Since then, my well trained love muscle has
given me and my lovers many wonderful and violent orgasms.”
