Thank you for your question. I understand this situation is confusing for you and that you might be afraid to lose your boyfriend, which is very comprehensible.
Sexual desires and preferences are different for each person. Preferring anal sex over vaginal sex isn’t a sign of homosexuality, and the same goes for having many gay friends. I think it would best to initiate a discussion with him and to share your concerns and feelings. Sexual orientation is a very intimate and personal issue and only your boyfriend can answer that question which is most important to you: is he gay or not? Talking things through with him is a good idea because it might help you understand why he relates better to his gay friends as well as learn about whether he is questioning his sexual orientation.
You seem to have a great relationship with your boyfriend and you did not report other important problems between the two of you. It seems therefore plausible that, if you express some of your concerns to him, he would respond in a positive way and possibly answer some of the questions you are pondering.
I hope this has helped you clarify the situation…
