This. I could see myself with someone who used to do it.
I could see dating someone who is currently doing it casually (hello James Deen) if I was not looking for serious commitment but I could not see being seriously involved with someone in that profession. Then again, like WhoMe? said, I don't think I would be happy seriously involved with someone who was in any sort of an entertainment/nightclub career. It would be an incompatible lifestyle for me, not just the sex but the hours, the public exposure in general.
