I asked one 20ish sp how or why she got into the biz and she said the following:
Guys her age were just boys and she liked MEN, so she got a lot of sex, with the type she wanted, AND she got paid for it...she said "why WOULDN'T I be an sp"?? lol...
I thought about it a bit later on and since an SP reserves the right to bail on any situation she feels uncomfortable with, she really didn't have to have sex with anyone she didn't want to (due to appearance, cleanliness etc) so....
Then I thought: she probably hasn't had a bad date yet but then again, from all the sp's I've talked to, the bad dates seem to be few(er) and farther between these days. I guess that is even more so when you work for a reputable agency....
