I would not conclude that the Mrs-to-be-hd had sex with hd on first date because she enjoyed physical contact. I think there are a multitude of reasons why someone might have sex on a first, second, third date.
Maybe she wanted to prove to herself that she was attractive. Maybe it was a buildup of tension that needed release. Maybe she was curious how hd would be in the sack. Maybe she had a bet with some girlfriends. Maybe she just wanted to get that over with so she wouldn't wonder every time they went out if "tonight's going to be the night." Maybe she felt the need to "score" for one of the above reasons or another.
I'm more curious if the sex early in the R was easy, playful, sensuous, fun... or if early on it became a power struggle, fraught with meaning, etc. If I'm remembering correctly, things kind of went downhill after y'all moved, right?
