wait i missed the post were you said you were a virgin and tha'ts it... cuz it' happened to me when i lost my virginity too... i really liked the girl, thought she was hot as hell... then we were sitting on my bed and she just lunges forward and starts making out with me and one thing leads to another, next th ing i know i can't keep it up, she starts sucking like hell doing EVERYTHING but once it was gone, it was just plain gone.
