<human>: Give me the gist of the text in a nutshell

21 Male, got to 2nd base with a 18 year old from a different college. However I have a girlfriend of 3 months.

Maybe I did it out of anger, but my dick lead the night. I'm not a huge partier, but I can drink. Some girls invited me out of nowhere, all attractive, ended up taking care of one girl who liked me and made out all night. Long story short, she ended up in my apartment and things started heating up before her friends came and got her, for better or for worse.

My current girlfriend, has no sex drive. Has never done anything and we hardly make out (more like 3-4 linked kisses). She canceled plans for the day and its all I was waiting for (I hardly see her, maybe 3 hours a week?). So I had a chance to go to a party (and alright, maybe get some action, who am I kidding). I wanted action, I can't even make out with my gf, and the girl that liked me at the party was all about hooking up. So I went with it. +1 for more experience

I'm a fat to fit virgin and it was just fucking nice to actually have a girl who wanted me. Plus, I had a brand new shirt on, form fitting (my first lucky article of clothing) instead of my old fat cloths and I felt fucking great, confidence was way high.

I don't know, its my first relationship and my gf is super busy and the semesters ending and I couldn't wait. It was a crazy party and a first for me to hook up like that.

I would like to think my gf is worth waiting for but, shes a notch or two down from the girl at the party. I think the semester will end, relationship will end with it. So maybe I am pulling the plug a little with this stunt. I will probably not tell her at all. 

No future possible with the girl at the party. Just a one night fling
<bot>: Cheated on my girlfriend, didn't get to sex. Girlfriend has no sex drive(don't even make out) and now I don't know what to do.
