So here's one for the guys: For a girl, attraction grows deeper with time. You may be cute on the first date, but you're pretty damn near comparable to Taylor Kitsch - see Friday Night Lights for reference - after you've cared for my sick cat while I was out of town or brought me soup and crackers when I was forced to stay up late cramming for exams. The more time we spend with you, the more there is to be turned on about. Unfortunately (and rather depressingly) I overheard two guys discussing the exact opposite of this at a pub today.
So you tell me: Does a girl really become less sexually desirable the longer you are with her?
