Well ... who wouldn't like a few rounds of "bend over boyfriend"?
Finding someone who enjoys doing this, or at least offers it, should be the norm and not the exception.
But don't be surprised if you ask a nice lady right off of the bat if this is something that she will do and she's a little shy discussing it. Any type of sexual penetration, for money, is an illegal activity. Most women are not going to like discussing it on the phone, or by e-mail, without some screening first.
And sometimes, even after that.
