I know the general things you should text to someone after hooking up, but there are some other details I am not clear on. Consider that I am a virgin male in college, so I am rather novice. I don't want to come off as an asshole by not doing something that is expected from me. Assume that this is a frat party hook up.

What should I do just after hooking up if I am at my place? If the girl lives over 15 minutes away and its night time am I suppose to offer her anything (such as walking her back or a place to stay for the night)? What should I say if I hope to see that person again vs. if it is a one time thing?
