Dude, some guys are working professionals putting in 80 hours at the office, or don't want the bullshit of a relationship, or have to deal with girls or have to worry about negotiating dinners for sex and other bullshit.
Sometimes you just want your fucking dick sucked right god damn now with no obligations, bullshit or questions asked.
And... that's when it's going to cost money.
So, basically, what you're saying, commenter, is that you're anti-capitalist, which means you're an anti-america, pinko communist scumbag.
/sarcasm
But, really, some guys just don't want to deal with the bullshit of women. They know what they want, they know what they're willing to pay, they don't want to have to spend hours and dollars on dates to get it.
You shouldn't shame a guy for knowing what he wants, and shame a woman for giving it to him. Bartering for sex is like the oldest form of bartering in the world. whores are just better at it, because they provide a $ figure instead of making you "date" them or guess how much you have to spend before you get some.
