For some very strange reason, there are always people, be it men or women trying to tell us-women what we can't and can do with our bodies. If it isn't abortion, it is prostitution. I think society as a whole needs to come to realization that a woman is more than capable of making her own informed decisions, and get over this patronizing 19th c. habit of treating women like children or brood mares; with out any room for the complex individuals that we are.
I hate to break it to them, it doesn't matter what they do, they won't stamp out prostitution. Drive it further underground, yes, but eradicate it, no.
I mean aren't there some more important issues to be dealing with, than whether a man pays for his sex?
