Hm, I don't mind people drinking at all, as long as they don't get drunk and try to hit on me or something. Initially everyone tried very hard to get me to drink, which is annoying, but these days its kinda a rule. They (my friends) accepted it and now I'm always invited because I'm always the designated driver
Sex has a LOT of appeal to me, but drinking has nothing. Besides, just knowing I'm there to make sure my friends get home, SAFELY, is good enough reason for me not to start drinking. They can drink as much as they want and know they won't do something stupid
