I understand the feeling: I'm a "good girl" in the sense that it never appealed to me to go out to bars or clubs... I would prefer to just relax and hang out with a few people in the comfort of our homes or apartments, etc. In college, it was really hard for me to find friends who shared these tendancies, especially freshman year when everyone was experimenting with their new freedom.
I found the best thing for me was to immerse myself with people LIKE myself. I moved to a chem-free floor, for example, which was inhabitted by people who, like myself, did not feel the need to use alcohol to supplement a good time. Also activities that I enjoyed, if I got involved in a group, I tended to meet more people I meshed well with. For example, I joined the college orchestra and met some great people there (two of which are still close friends of mine today).
I hope it works out! good luck
