A friend of mine went through an escort phase about two months ago. 2-3 escorts a week. He grew out of it very quickly, a month or so...I think he may have realized he was beginning to spend more that he should..., but afterwards, he had no problem picking up women. I think that after you engage in such practices, there is a certain "I really just don't give a fuck" air about you that really works, because as far as I can tell nothing else really changed.
Yeah, but you're in Korea, right?
That's illegal everywhere else.
Besides, you'll probably catch something.
