Hm. For me to drop my pants, no questions asked, I think it would have to be a guy or girl who's on my freebie list. You know, the lists you and your significant other have that say if the opportunity presents itself to hook up with the people listed, you can go for it and the other can't get mad at you for cheating. Beyond that, I'm not sure there's a whole lot you could do. I tend to like to know the people I bang.
