<human>: I've known Alex for a couple years through friends. One of my good friends, Mike, used to live with him and they both work at a bar that my friends all go to fairly often. He's a really nice, fun guy, but he's also really hot and can get most girls he wants. When Mike lived with him, he said Alex would usually have a couple different girls in every week, then out the next morning.

I slept with him last week after bumping into him on a night out. I was out with my friend George, who knows him better than I do, and he'd randomly mentioned Mike in conversation and I told him he was really hot and I couldn't care less if he was a man slut, I'd still tap it. Later we went to a club and saw him unexpectedly and George told me that Alex asked if I was single, blah blah blah. Skip to an hour later, we're having sex in his flat.

I don't want a boyfriend at all. I've just come out of a relationship and I don't want anything even remotely exclusive or committed. I'm going abroad for a year in a couple months anyway. I genuinely just want to have occasional sex with this guy, because he's really hot and a lot of fun. The problem is I know he can get laid just by looking at a girl, and I worry that if I suggested a FWB situation he'd think I was desperate and trying to sneakily make him my boyfriend. He told me I was great fun to hang out with, and I've seen him since we slept together and it was brief but not at all awkward. We know a lot of the same people though, and if I asked to be FWB and he said no, and it got out, I'd be mortified.

What do you reckon /r/relationship_advice ? Should I be upfront, or just hope for the best next time I see him? Or just chalk it up as a win, self-high-five and let it go?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: Banged a really hot guy last week, want to be FWB but fearing rejection because this guy has super-panty-dropping-powers.
