I feel like a loser compared to my girlfriend?

I'm kind of a serious guy who values school and all of that crap. But when i hear my girlfriend talking about how she used to have wild parties and how she cheats on every test and all of that rebelling stuff. I really feel like a loser.. I love her a lot and she says i'm not a loser, but I am compared to her. What should i do?
