19 year old virgin, how do I deal with the mental setback?

[Reesays]

So this weekend got pretty wild. I met with a friend for a house party and managed to see this girl I met my second semester of college. She is a White brunette that tans easily, says she has a lot of native American in her that causes her to be that way. She has light brownish hair with green eyes and a cute face. Now I was at this houseparty, for an hour I talked to people and danced. After an hour I got the guts to talk to this girl and she asked me how I did in the class, told her I got a B, she said she got the same thing too. We catch up on life and after like 5 minutes of talking to her, I disperse and talk to other people.

She is talking to her friends, 2 hours into the party the music is dying down and the girl is still around but most of her friends have left. So I walk up to her, start talking to her again. It is like there are 6 people left at the whole party and when we are talking, there are maybe 4 people in the room. My friend whose house this party took place in is kissing this other girl, that left the two of us. Now the thing is she says she is tired and tackles me on to my friend's couch.

Not really tackling but leans on me so hard that I land on the couch. Now she is close to me, we are face to face, talking and I close my eyes for a second and open them and smile at her. She laughs and says "if you want to kiss then that isn't the way". I go for a kiss, we lock lips for four seconds and then I let go.

Then she asked me why I did that, I tell her this time lets go for as long as we can. We do just that, it was longer than 10 seconds and I think she must have felt my tool touch her or something and she grabbed it and started doing what women do with their hands. I put my hands in action and started to do what men do to women with their hands when they are making out.

So I hear a shout, my friend said that if we want to do that stuff, we are gonna have to do it at our own house. I tried to argue for a bit but he said "MY HOUSE MY RULES". So the girl is still on me, I carry her to my car and ask her whether she wants to go to her apartment or what. She just grabs me and kisses me and I still had not stuck it inside of her. So when she starts to jack it harder and faster, I could not hold it in and a load blows.

So CLOSE......

I get a bit sad, she smile and says "lets try it again some other time". I was like "=("

LIFE SUCKS
