Simple common sense approach seems to work best. Courtesy, manners, a willingness to do the simple things like the shower upon arrival even though you've showered, shaved and are well groomed and clean. Why anyone would contact a woman in the first place if he can't afford or doesn't like her rate is utter stupidity, imo. Read her ad thoroughly and her website if she has one and of course, when I say "read", that doesn't mean go to her photo gallery and jerk off only, lol. Although, in all fairness, sometimes those photos are awfully damn sexy and it's difficult to restrain oneself.
. Guys, treat the lady with kindness and respect and honor her simple wishes and you will have a wonderful encounter 99.9% of the time. That should be obvious, of course, but as we see by the earlier screenshot in this thread, self entitled douchebaggery exists and these reminders do help.
