Funnily enough I thought in britain it was legal, or is it? I remember this guy in my class at uni said that he slept with two prostitutes over the weekend ages ago, and I just laughed for ages, but I wondered if it was even legal.
But i heard that over in the states (in one of the southern ones i believe) that they have cathouses (I remember seeing it on channel five lol) that have prostitutes in there and all seems fine and dandy. everyone is checked, there is order and no one is getting exploited. If all forms of prostitution were like that, in a controlled environment, then there would be no problem with it.
I also think that when people say prostitution is degrading to women etc, that for some of the ones that willingly do it, it is a conscious choice and they know what they are getting into, it is sometimes a stepping stone for other ways of life. And if they do so choose it as their ultimate way of life then what is the problem? some clean streets, some clean toilets, and some sell their bodies. There are other opportunities out there for them but that is for them to decide.
