<human>: My bf and I have been together for about 2 years and are living together (for about 6-7 months). He's a musician and plays shows all weekend usually at bars until about 4am and I kind of got sick of seeing girls hit on him so I stopped attending them to benefit our relationship so I wouldnt get so jealous.

These past couple of months have been hard as he has stopped paying attention to me sexually (I pretty much have to spend an hour coaxing him once a week and even then its 60% chance he'll just pretend to be doing something else) and when we go out he openly flirts with, say for one example a young, pretty musician [18/f] infront of me and when I speak about it to him he denies it.

Then today, I was browsing his email (we are open with our accounts for emails etc) so I could use his League of Legends account since mine was temporarily banned and I had forgotten his username and password, only to find 6 or 7 emails from adult friend finder. 

I laughed it off since I thought that he would have made this wayyyy before we got together. But then I noticed he only got the emails recently so I looked him up and for sure there he was. 

He had only made the account 2 and a half months ago.

I have no idea what to do. He comes home in a couple of hours and I don't know whether or not to ask him about it. Surely a relationship is built on trust?
