Because women's nipples are sexy and men's aren't.
Ick. I think I need to wash my eyes out just thinking of it.
No, none of my concerns are related to the illegality of prostitution and none of the concerns would be alleviated by making it legal.
Johns will pay extra to ride bareback if the law allows prostitution but requires condoms. Even if prostitutes are protected by trade unions Johns will pay extra to beat prostitutes, pee on them, or do other things that sick human beings do to people they purchased. Legality would not change the fact that almost all women who go into prostitution were abused and started prostitutiin as a minor at the direction of an older male. It doesn't change the fact that to be able to live the lifestyle of having sex with 20 stinking, violent overweight johns a day you have to be high.
Healthy human beings do not engage in sex with strangers for money. Do not challenge my feminist credentials. I belong to the post-feminist critique who fully understand the duality of objectification and reject it. I can sloganeer better than anyone on this board. But that doesn't change the fact that anti-prostitution laws are a human rights protection scheme, not a patriarchal legacy keeping the woman down. Woman should be free to decide who they have sex with when they want it. Prostitution is an anathema to that value.
