I think there are a few misconceptions about it. It looks so simple when you watch a movie with it, but if you watch Family Business or something similar, like, behind the scenes, they talk about enemas etc. - Really puts it in perspective though.
Ive never tried it, but most girls I know or who Ive talked to about it said theyd be too scared that itd hurt....I wasnt going to pressure them into it. Yet some women seem to genuinely genuinely enjoy it.
