I skipped half the thread a bit after MRD won it but I think PVC had a good point as well, if she is up for some kind of one-night stand, I'd make it clear to her that that's what you want, if you lure her into thinking you really like her and want a relationship and then drop her because you were just out trophy hunting of sorts(that's what "getting into her pants" sounds like to me), then I would wish noone had given you any advice to be honest.

Oh and no, that's not my advice, I have none anyway, I don't need a woman, I have a computer.
