I've been with prostitues. In my car and outcalls to an earlier apartment. But not for years. It is costly and I was earning more then. I always used to ask permission for things. Like "Can I grab your hair?" or "Is it ok if I slap you on the ass and call you 'bitch'?" More often than not they seemed amused and I fancied myself as being a sweet guy, but looking back on it I'm not so sure.
