boyfriend advice asap!!!!

sa

just recently my boyfriend gold me that he wants to go to parties. he said he feels tied down by school and at home...that he wants to to loosen up with classmates. I trust him but I don't know who is going to be there. I'm unsure about it because he never had an interest until recently. if he gets drunk and poof he doesn't know what he is doing, he could end up cheating. And I asked him why put yourself in that situation? and he didn't answer
