It's easy. All you have to do is appreciate women, be honest, be upfront, be yourself and be direct, and of course the a few hundreds to pay for the night.
Hehe, yeah there is that. XD
On a serious note though, prostitution is still illegal and therefore dangerous in a lot of countries, and even where it's not, sex with a prostitute may not be helpful, as it doesn't feel earned and has no intimacy. Kinda like eating cardboard won't be much help to a starving man.
