<human>: Can you give me the gist of the text in a nutshell?

I'm not sure this belongs here or not, so I'm terribly sorry if I'm not allowed to post this here (I just don't know where to post it, honestly),  also this is typed on mobile so I can't see sidebar or type/ format this nicely.

Like two weeks ago I( 16m) started in a gymnasium and there's been a lot of parties, anyway I'm at this party and meet this girl from another school (was in 10th grade so she'll be going to a gymnasium next year, maybe this one, probably so since this gymnasium is an English one and she is going to a really expensive English school also), we chat for a while, then I walk around and introduce her to some people, then when we're walking around I say, actually I just want to kiss you, then we make out for a while, then we walk away from the party and make out there for a while, then stuff progresses and we have sex, after 3 hours later when we're done we walk back to the party with arms around each other. Once where back at the party we sorta get separated by our friends (they both come from each way) and I go home shortly after as I'm tired and drunk.

Anyway, this was two days ago around and I'm wondering whether it was just a one night stand (or more) and if so, should I add her on Facebook (One of her friends added me out of nowhere, so I'm curious) or not, or try to hook up (since she was quite cute)
<bot>: Met a girl at a party, had sex, went home soon after. Wondering if it we should regain contact.
