Is my boyfriend just not into men as much as I thought? / Small Rant / What should I do?

Tl;DR Boyfriend views straight porn, insults me, and says he's asexual. Maybe overthinking it?

I'm a rambler, so if you hate that, run while you still can. My boyfriend (M22) and I (M21) have been together for almost a year, known each other for 3. We decided to move in together and everything was fine besides the occasional financial stressors or hygiene issues. (I have OCD but that's not what this is about) Before I moved states for him, he mentioned he was asexual, but occasionally participate in sex. He also mentioned he liked men over women more, despite most of his partners always being female. (He is pan, I should mention) I was okay with all of this, completely and I genuinely love this man to death. But within the following months he would drop crazy lore about people who he'd either hook up with or was previously with. I was open about it despite it making me uneasy. I wanted to be mature. But from my understanding, he was very promiscuous and had quite a lot of three ways and other flings. Which I didn't care for but supportes him completely for, because it shouldn't matter. I should mention also that he wanted to wait for sex, again completely okay and found mature of him. He stated about half a year to a year (which was discussed a few times because we have different drives and was trying to find what would work for the both of us). I would occasionally get on his phone before I had a working one of my own. Sometimes listening to music, videos, or occasionally getting on his reddit because we like a lot of the same stuff. He looks at a lot of hentai, some yiff, and big chested women. Which didn't bother me, it seems like he has his preferences like anyone. But remember what I said before? He said he liked men a whole lot more. I come to find out this isn't physical unless they're a femboy, which I do not look like one, even with estrogen and clothes. For those who do not know, estrogen causes penile atrophy. Anytime we would cuddle, sometimes I would get erect unintentionally. He would say this, "can you get your thing out of the way?" Which hurt, obviously. Often we joke around, stupid stuff really. Almost never does it go overboard as we never insult each other but have dark humor(the good kind, not the racist shit). But I made a joke that he practically set up with few words, one about me being deep in him. Without hesitation, he said,"What? 3 inches?" First off, 5 inches. Second off, I never commented on his appearance and typically he doesn't when we joke. Yet if you say these things straight faced, it starts to look like you're simply insulting me. Not to mention he said he really likes to shower with his partner, saves water bill, ect. We shower together, first time for us ,but more importantly me. He acts weird about it while I'm the only one genuinely washing myself as he stands in the water most of the time. I obviously finish before him and dry off while he enjoys his shower on his own. Afterwords said it was too small of a shower to be doing that. Which honestly felt like a bit of a blow with all these comments. Now I should mention a few final notes before leaving the post. Yes he does love me, has shown he loves me for me (maybe just not my body?). He mentions how, without me, he wouldn't be where he is and would probably be at his parents. Shows appreciation through kisses and words of affirmation. He's autistic as hell, and I've learned which reactions mean what. Which is genuine or simply something else entirely. So with all this said, what the hell am I supposed to do? Am I overthinking the situation? Yes we are young and we moved in together somewhat early, so I can see us bumping heads. But my question is do you think he is at the least bit attracted to me? He's into skinny big chest women. I'm a slightly chubby big rear man trying to be feminine(which only works with makeup and clothes, ones I don't have.) Also read me to filth, if something I said is immature or I need a new view of something, go ahead. Tear away.

Thank you for coming to my ted talk. <3 Love you, strangers, and stay safe.
