In life? Or as sexual conquests? The answer is the same for both, and they don't count as sexual conquests. Unless the quest was to get aids, then hey, you win!
Jk, they count. But only if they're hot. What good is an ugly hooker? Being aroused is a requirement and if you're not only going to pay for an ugly hooker, but get turned on by one, that says more about you than it does about her. You're as desperate for sex as she is for crack. There are no winners when we're talking about ugly hookers.
