...a few minutes? Don't men realize how 95% of women long to feel safe and secure in a man's arms and that they can make a girl feel so good by just hugging her for a little while? Instead they have to have sex with her and then just walk away without caring that she feels really crappy after that. It doesn't take that much effort to cuddle for a minute or two
That's why some girls have casual sex in the first place. They want to feel that closeness to another human being even though they know it won't last past that night. She gave you what you wanted, why can't you just put your arms around her for a little while? I don't see how this is asking for too much.
