Hi, I am a straight guy. I orient myself with being straight but I also am attracted to guys too. Anyway, I have a friend who I think may also be curious and I am very attracted to him. He makes jokes about oral sex with guys. A couple times he balled his fist and looked at me as if he was giving a blow-job. One time I offered to do it and he said "don't play with me that might turn me on too much." and so I jokingly moved towards him and he said:" whoa what are you doing?". So I said I was just playing but when I was leaving he jokingly said: "maybe tomorrow". Also, we watched porn together (no masturbation) and he made comments about the guy's penis. And one time he had shorts on and I pulled them down jokingly and turned and walked away so he was naked and told me to turn around and I saw everything and he said "that's what you wanted to see isn't it, God!" He said it like he was embarassd and joking. We only flirt when we are alone. How do I know if he discreetly wants to take it to the next step?
