Is there a way this guy's straight?

Hey all! New here, but have been lurking for around a month. I'm just gonna start the story (warning: it'll be a long read) I'm gay but haven't come out to ANYONE (not even somewhat to myself) but i'm 24 and when I was 20 yrs old, I made friends with this guy at school who was 2 years younger than me. We would get high and because I'd get paranoid and didn't wanna confront my parents when high, we'd chill until I felt fine enough to go home. One time, he asked me to come over and stay the night and we would smoke. I'd always been at his place but never slept over. So we did one night. Everything was going well, and we were pretty good friends, really close, knew a lot about each other. He had always been the horny kind always wanting to get at every girl (unsuccessfully) but he wasn't bad looking, he just wasn't successful at it. He had had sex with other girls and had done a lot of things with them that I didn't (I'm still a virgin, but I don't mind). That day we planned to sleep in his basement and there were two mattresses on the ground beside each other. We smoked, usual stuff, then when it was dark and we were lying down, he started to get really itchy everywhere. He kept scratching and we were just playing video games, and I offered to scratch it since we were really close. To be honest, I always thought his sexuality was questionable, and always wanted to bang him. So he agreed to let me scratch him, and I started scratching his back (through under his shirt) and slowly started going down and started rubbing his ass, and he didn't mind. He kept telling me to keep scratching and I kept scratching between his crack, but he'd stop me right when I went for the asshole. This happened and we didn't speak much about it. I slept over at his place a lot of times after that and this happened a lot (but would never extend beyond me rubbing his butt and he'd never let me touch, see, or do anything to his junk, or ever reciprocate more than flicking my nipples and pulling them). He would call me gay and I would brush it off. One day, we got super drunk and I was lying down on the couch on my phone, and he came and fell on top of me and started sucking my nipples through my tshirt. I grabbed his ass and leaned him forward and tried to take off my shirt but he said no and he got off. We never spoke about that ever either. After that, one time there was a rumour in our friend group that a girl he sent dik pics to told people he had a green dik head, and we all made fun of him for that. I always kept making fun of him for that, and one day he got really mad and sent me his dik pic and he's like "you see it? no green," in return, I sent him a pic of mine, and we never talked about it either. A year later, the whole sleeping over thing and me rubbing his bare ass kept happening almost every 2-3 weeks, and one night I went for the hole, and he got up and punched me and kicked me out of the house and never invited me over, and we never talked about it ever after. We sort of had a fall out relating to a different matter, and we don't talk to each other anymore, but it's always on my mind, whether or not he was a closeted gay just like I was? His parents thought I was gay, and his dad almost walked in on me grabbing his ass one day. If you think he is, would you give solid reasons to support why he might be? He is in love with girls and is always getting pics of girls naked, but he has never had a real relationship. Is there any way he is 120% straight and not bi or gay?
