I was thinking about this the other day. BUT it's better its illegal. Yes, as much as I want it to be legal it's better left alone. Women hold too much power for sex. If legal you'd see every woman selling themselves to make money, things wouldn't be about relationships or having sex with a few guys. Women would be whoring themselves out for money to get anything and everything and guys would sucker to them. Having sex would no longer be something you and your wife or girlfriend share, chances are she'd be selling her body to pay bills, or just for the money..
Can you imagine women having an even lower motivation to learn be educated, get a job, etc.. Next they will just be having sex for money, and not worrying about a single thing. They will hold too much power over men..
There's another really really good reason but I'm tired and can't remeraber it. It's such a good reason that even as an advocate for legal prostitution I had to change my views.
