Sex too soon?
So I met this guy 3 months ago at a rave, we've been texting all day every day since then. I send him my writing, he tells me his ideas - pretty personal stuff. He'd say things to me like 'you're the most interesting girl I know' and get jealous when I mentioned other guys. Yet we never met up - it was all a bit weird. Until last night. We met up in my area of the city we live in, had some drinks, made out a lot, he missed his train home and stayed over at mine. He wanted to have sex, but I said I was worried it would make things complicated so I gave him some hand love instead and we went to sleep. This morning we had sex - it kinda just happened, I don't know. Afterwards we hung for a couple hours spooning and chatting, then he got a cab home. He whatsapped me a couple hours later making the same kind of chat we always make on a day to day basis.
So my question is, have I fucked it by having sex with him so soon? I know he's not boyfriend material, but I do like him and I'd like to have a kind of fuck buddy thing going on with him, but I don't want him to think "been there, done that" as he is very attractive and I'm sure he finds it easy to get sex. We've been talking for such a long time that I guess I felt like he'd gotten to know and like me enough as a person, but now I'm worried we won't see each other again. On whatsapp we were talking about how many people we've had sex with and he saidd 'tbh though I get bored of meaningless sex' - I didn't press him as I didn't know if he meant he is bored of nights like last night (or this morning rather) or if he is currently looking for more than just meaningless sex.
