Am I gay?

I've been friends with a guy for awhile and I don't necessarily feel a attraction besides a friend besides always wanting to be with him. He is gay but he has expressed that he has no feelings towards me but I'm not sure if that's true or simply just cause he assumes I may flip out if he says otherwise. I have wanted him to do oral to me but I don't see anything besides that. I'm pretty sure that would mean I'm bi. He talks about other guys by me which doesn't bother me and has actually blown a guy when I was with him and I didn't really care, I wasn't jealous or wish it was me. Any advice of what I should do or any questions you have that need answered let me know. Thanks
