Sadly,
The thing I hate about the porn industry is it pushes all these myths that make men think that women work differently than they actually do....So guys do things and push for things that are, well, just wrong! And hurt and are a big time turn off and trust breaker.
So while the porn chicks are 'acting', they really hate it as much as those vanilla wives at home.
Gals, I wasn't raised in a puritan bubble, but I have ~never~ heard any man ask or display interest in doing this, nor have any of my friends. And conversations have been had that are close enough to the subject that I think it would come up.
I'm just sayin' is all.
