...Yet loads of girls offer €100 for just a quickie wash 'n' wank, and get plenty of takers?
I tend to feel, fair enough, that the answerers of the question have, of course, a vested interest in giving a low fee!
Time irrelevant, as you say, isn't really the case though, is it? I mean, what someone would pay for an hour of proper massage with a happy ending, as opposed to a quick in and out, will surely be different?
