Ok, so I’ve suspected my friend may be bi/gay for a number of years. When we were in middle school he tried to touch my penis and one night tried to spoon with me when we were roommates on a school trip. Then about a year after we graduated from high school we were parting ways after hanging out, and out of nowhere he flashes me his penis and presses it up against my car window, laughing it off like it’s nothing.  Now, we’ve started hanging out again about a year after college and things have escalated. I’m confused though because I know he is attracted to girls, as he asks me for relationship advice and tries to talk to different girls. He also had a long distance relationship with a girl that he cared about but turned out to have a boyfriend the whole time! I know that he was crushed over that loss. Through reading some posts he made in an online forum, I know that he has never had intercourse but has performed sexual acts with girls. However, before each date or outing he always gets drunk. Similarly, when we hang out or he gets drunk he shows me his penis. In one particular instance, he asked me to keep the door open to talk to me while I showered. I agreed, but felt a little weird about it. Recently, when I was over and he was drinking getting ready to go out on a date, he told me to talk to him while he shaved his pubes and tried to get me to come into the bathroom while he was showering. I declined, but stood outside the bathroom and talked with him. After the shower he was talking to me about penis size and told me he his size. Wanting to one up him and feeling some sort of male superiority I told him that mine. He called BS but said he was jealous. I’m beginning to think that that was a mistake now, because he may have misconstrued our conversation to mean I was interested in him. After that he continued to talk about his size and asked me if I’d seen his before. I reminded him that he had flashed me on multiple occasions when he was drunk. He pretended like he didn’t remember and asked me about his identifying features. Then he showed me his penis again. I’m secure in my masculinity and am straight with a long-term girlfriend, but I’m beginning to wonder why he may be trying to flirt with me or whatever it is that he’s doing.  Today he asked if I wanted to video chat for a minute and I said yes. He was in the bath tub and pointed the cam towards his crotch and said, “Oh, you can’t see anything!” Then later he asked if I wanted to see his penis. I told him, “No, I don’t want to see that!” I had this faded look in his eyes which made me believe he was drunk, but when I called him on it, he said “No, I’m completely sober” while giving me the finger. He’s an attractive guy and he has girls that are attracted to him, but he seems a bit socially self-conscious and tends to over-think relationships. That is why he comes to others for advice. He was in a frat in college, but I wonder if that may have been a cover. He’s outgoing and jokes around a lot despite the fact that he gets nervous when dealing with romantic relationships with girls.  Do you think he is gay or bi? Has he been attracted to me or thought I was gay/bi all these years? Does the fact that he gets drunk before every date mean he’s nervous, or that he’s gay and trying to make himself act straight?  I like my friend and value our relationship, but this kind of weirds me out a bit. This week he asked me to come over in the morning to help him move a piece of furniture into his room. We’ve been hanging out pretty often since he came back from college this past year and it’s pretty chill. His behavior kind of throws a wrench in everything though. I’m wondering how to tell him I’m not interested without making him think that I think he’s gay. Even if he is gay/bi I don’t think he would admit it because of the social stigma attached.  I mean, I can admit when a guy is attractive and can be visually attracted to other guys, but the thought of sex with another guy does not turn me on at all. I feel confused, as I’ve never had such a situation come up like this before and don’t know how to approach him.
