Yea I think I am in the same situation. I am bi and my friend of years I think is bi but is trying to resist it. I say this because he wanted to compare sizes and feel each other for size and he was hard as a rock. then I brought up blowing each other and I said I would blow him first he said yes and replied I wouldn't turn that down. so I blew him and he cam in my mouth and I liked it and he said it felt great but he said he didnt think he could blow me. So I think he is bi but is afraid to do anything because he might like it.
