<human>: This is probably a stupidly basic question but I've only been sexually active for a year now and I've been realizing recently that I am super super bad at reading men. I am likely on the high functioning end of the autism spectrum, which does not help. 

I'm not really interested in a long term relationship now but I want to hook up with people who respect me and I can have interesting conversations with... Maybe like a long term friend with benefits. I'm fairly good looking so I don't have a problem getting men interested initially but it always turns out the same. They meet me, act interested in me, tell me that they think I'm super smart, funny etc. I get swept up in the attention, hook up with them, and then realize too late that they were feigning interest to get into my pants, and they don't call me back, or maybe only once or twice, and then it's over.

I know the obvious thing is to stop hooking up with people so fast after meeting them, and I'm going to try to do that. But I don't know what the next steps would be. How long are you supposed to wait before you decide someone has good intentions? 

Books, TV, and observation taught me most of what I know about social stuff, but my normal approach is useless here. Any advice would be much appreciated. 

(Also: I've already tried OK cupid, and it was a nightmare :-S)

Can you give me the gist of the text in a nutshell?
<bot>: how can someone with high functioning Autism spectrum disorder tell when a guy shows genuine interest in a long term hook up, or when he's just acting interested to have sex?
