Don't you feel bad that you are having sex with what can be assumed are married men?

I don't feel like I do harm the lives of others, no. In a lot of ways, I see what I do as harm reduction. My clients are going to cheat, but when they cheat by seeing me, they're with someone with strict rules about safer sex, who isn't going to involve herself with them emotionally, who isn't going to show up pregnant and break up their families, who is going to encourage them to treat the people around them well. If I wasn't in this business, they'd still be cheating, just like (extreme comparison ahoy!) junkies will still shoot up even without sterile injection sites, but it's better if they do it as safely as possible.
