Did I used to be homophobic? Am I?

Right now, I am honest-to-God trying to get better. I know there's something wrong with my brain and I'm trying to fix that. I try to be as supportive as I can to LGBTQ+ people and I don't mind if they outright say "I'm gay/bi/whatever" or "I have a [partner/spouse of the same gender]" but something about having to hear about romantic or sexual stuff with two women really doesn't sit right with me, especially with "yuri" or having lesbian relationships portrayed on TV. However, "yaoi" and gay relationships on TV I find awesome and cute, I'd say. Men, I find attractive, though, so that could be why. If a guy talks about his romantic or sexual encounters with another guy, I don't mind at all.

While trying to convince myself I was bi or pan, I would hang out with a lot of straight women, crush on only guys, and even hang out with homophobic women.

In high school, my best friend was a homophobic and transphobic girl who relentlessly bullied one of my bully victims: a trans man. I tried to convince the guy it was his fault he got bullied, but I have matured and see the best "friend" was just an asshole.

Please, no judging, I am only curious.
