I started fairly young and took a long hiatus. I don't know how much was just maturing as an adult and how much was due to prostitution.
However, I take very little shit from men. I remember, once, years ago throwing a one-night-stand guy out of my flat because he was pestering me for anal. "I can't cum without it." "I don't really care if you cum or not."
I do still enjoy the occasional ONS, but haven't recently. I like to be selfish and do what I want to do for me. Maybe *I* want to perve on and objectify a beautiful young body for a change.
I am not bitter about men and think they all cheat - I am more sympathetic if anything. I have learned that nice men can just want no-strings sex and they've figured out paying is the surest way to avoid emotional entanglements that hurt the other party or endanger their families. I also know that men can be starved for affection even if what they think of as affection is a blow job. And I've learned that men will deal with stress with sex. Like, a woman will have a terrible day and want to A) talk to a friend about their feelings, B) eat some chocolate, and C) watch Sex and the City with a bottle of wine. Men may well say "I want to drain my balls."
