OK, so why DO men frequent prostitutes?

[Xithras]

23. A combination of fun and loneliness.

There are a lot of people in this world living very lonely lives, and humans are social creatures with a real need for contact with other humans. For many of them, seeking out a prostitute is a respite from that loneliness.

Then there's also the fact that fucking feels good. In that regard, it's no different than smoking pot, having a few beers, or even jumping out of airplanes and racing cars. People do all sorts of things for no other reason than the fact that they're ENJOYABLE. Sex pretty much ranks at the top of that list. Paying a bit of money to do something enjoyable is a pretty standard thing in our society.

IMHO, most Johns fall into one of those two categories. There are probably dozens of other reasons why men see prostitutes, but the bulk of them fall between these two.
