Never ever ever.

Ever.

Reasons why I'd never pay somebody for sex:

1. Most prostitutes are ugly.
2. It's really really desperate IMHO.
3. I hate the very thought of paying somebody for sexual pleasure.
4. Even if I was desperate, I have Mr Right and Mr Left to keep me company on lonely nights, and the only thing they ask of me is I don't use them too much or I'll get a RSI.
5. Most prostitutes are really ugly.
6. I'll thinkof something...
7. Most prostitutes are really really ugly.

Reasons why I would never except money for sex:

1. That implies I don't want to have sex with the person, and I'd never have sex with a person I don't want to. If I did want to have sex with somebody and they wanted to have sex with me, I'd probably just go ahead and have sex with them, I wouldn't ask for a credit rating!
2. It'd make me feel cheap.
