I personally don't see anything wrong with the act itself. If I came to the point in my life, where I was working all the time, hadn't found a girlfriend and couldn't find the time or effort to go and pick up a girl in a bar; then i'd pay for sex. I don't see what's bad about it, or why it's 'pathetic' or whatever other nonsense you can come up with. To be honest, if you account for the amount of time and money spent on buying the girl drinks in the bar before you sleep with her, it makes the £200 you pay a prostitute for sex look a lot nicer... and the latter is most definately the best bet. Why? You have no guilt about leaving her, you've paid for a girl who's got a lot of experience and whatever you fancy, she's probabally bound to do it.
I'm totally against the whole idea of brothels and all that jazz, since you don't know who'll end up getting your money. However, I see nothing with a private escort you've found on the internet, who's simply selling the good looks God gave her.
However, having said all that, it's certeinly nothing to be proud of(quite like masturbation).
Also, no one labelled Ronaldo, Nani and Anderson 'pathetic', etc when they paid for a big hooker ball at their mansion haha.
