Huh,...you know I just read my previous answer...and it did seem sort of a cop out. Or at least it seemed that way. That's not really the standard I want to set for myself.

Now I still would never have a threesome because any partner of mine still would deserve my full attention. I'm also not a mindless willing have sex with anybody all the time freak either. For the sake of this question in a purely hypothetical sense if I was some guy that was totally sexually active, had no inhibitions, had every women in the world willing to throw themselves at me, and had a gun to my head making me choose I would go with:
Actress: Jennifer Lawrence
Singer: Lzzy Hale
Pornstar: Sunny Leone
Not that I think about it I also think I coincidently got all the hair colors covered. That has to be a bonus doesn't it?
