Never boned a hooker here, and among the reasons above, I'd add my own that if I don't like a girl, I can't possibly bang her. If I just think she's a bottom feeding hooker, I can't get it up. Not only that, but does the hooker REALLY want to have sex with me? no. She's not enjoying it, she's just wanting me to hurry up so she can move on to the next cock and the next few dollar bills.
To each their own I guess, some people like men who dress up as women and get surgery to get fake tits.
