I was friends with this hb for 6 wks and finally got her in bed by saying you're not my type. (it really works) We had sex everyday for 5 days straight and she said I was amazing in bed. Well, long story short, I acted like an AFC and she didn't want be with me anymore.

It's been a month and a half and she hasn't been with anyone either. I found out she wants to get back with her old bf in jail who treated her like shit. Funny thing is, she got a loan for a lawyer cuz he's in there for 4 years for drugs.....I know. So anyways, I have no interest in this dumbass chick anymore, I lost all respect, but I really like the sex we had.

How do I ask for casual sex but I don't want her to think I want to date her again? Or her thinking I'm obsessed with her. Should it be like the Seinfeld show where you don't call the next day and spending the night is optional? How do I do it?
