Please i need your advice,i am worried

So two weeks ago i was on a girls vacation with my best friends.There i met a guy and we started kissing.I was drunk,i drank like 5,6 gin tonic.However,i remember a lot of things.When i talked to this guy that i kissed,i remember talking about his friends,his ex,what his parents do for living and stuff like that.Then I remember getting to the hotel with my friends.I have bad ocd and now i am panicking if it is possible for me to had sex or gave a blow job to this guy while i was drunk and not remember it.Is it possible what do you think?I am trying to explain to myself that if I remember what we talked about then i will surely remember having sex or giving a blow job,right?
