I debated whether to put this in the "love and dating" or the "social skills and making friends" forums, since this is about a friend and not about dating, but I decided on this one because this is one of my friends who I have love for and since sex is usually talked about in this forum.
Here's the situation: I've been friends with this guy for over four years, and I trust him, but for about two of those years we weren't in contact because of an unavoidable situation on my part (I wasn't able to see a lot of my friends during that time). We finally got back in contact a few moths ago and recently we were able to actually see each other. The first time was with other friends, but the second time was just us two. I wanted to get to see him again before he had to leave town, and that was good, but I had one of my random spells of extreme horniness while he was there. I don't like using other people to satisfy my sexual urges--that's one of the reasons I don't watch porn or masturbate about actual people--so I told him I was horny and moved away. He was really nice about it and said it was fine, and eventually we had sex (friends sex, not dating sex).
I was kind of bad at it and I felt guilty for some of the time because I was worried that I was using him or molesting him, but it was really fun. I think he might have thought he was bad at it too because at the end he said something like "Sorry you didn't get to enjoy that as much as I did" but he was actually really good and I told him so. It was also kind of a relief for me since it was the first time I'd had sex since a certain traumatic event had happened, and I was worried that I'd freak out the next time I did it, but for the most part I was fine. After a while I went home.
My question is this: What do I do now? I mean, in terms of social skills? I texted him once saying I had fun and I was sorry for the horniness and he sent back saying it was fine (and "lol"). (He usually sends short messages because he is bad at texting--I am too, so I understand; I JUST learned how to make punctuation on my phone!) I don't think he lied to me because of what he said about enjoying it, and another thing he said about having had dreams about it in high school (when we met), and because he knows about my Autism and how badly lying to me can backfire. But now I'm not sure what to do. I don't want to freak him out or anything, and I sense that this requires a bit more finesse than my ordinary "say whatever I'm thinking whenever I feel like it" technique.
I realize that some people stop being friends after they have sex, and I don't want to do that because I like him as a friend, not just as a person to have sex with. I think he still wants to be my friend too, since he said I shouldn't tell my parents what we did when I got home because they "might not let us hang out anymore" (I'm eighteen, and he's older, so it's legal) Should I send a message? Should I try to see him again before he leaves in a week, or would that be too inconvenient? If I do send something, should it be an attempt at humor, or should it be what I'm thinking (like usual), and should it be short or long, etc.? I have never been in this situation before. I also don't know what he wants me to do--note that he is Neurotypical, not Autistic.
So...yeah...what do I Do?
