Ex-husband seems to be confused about his sexuality

General

My husband and I are recently divorced and two months ago we decided to reconcile and he moved back in with me and our two children. He has told me about two male dates he had where he met them at their homes or they met him at his. The latest is that he went out with what he thought was a woman and upon fooling around, discovered it was a male! He says he only wants to be with me, but I think he is very confused about his sexuality and has been for sometime. I just don't know if I can live with someone who is obviously attracted to males. He says it is a turn on and it is only something to do to mix it up a bit........Any advice here?
