Any female really. I'm sure I can control my hormones for a single night, I've been to get together with attractive women before and we all just fell asleep on this cot/bed thing, I was never tempted to try anything. Seriously, it's kinda weird. Like an off and on switch. Really useful when trying to remain objective with a member of the opposite sex(I don't recommend ending a relationship with a girl's boyfriend because my hormones told me to attempt to procreate with someone, I give legitimate and objective advice).
