Varying levels of sexuality?

So I’ve SOOCD since I was in 8 th grade and it got really bad when I had an intrusive thought as to what if I was bi. And ever since then I’ve had self destructive behavior to where I would think the thoughts on purpose or about women and checking them out and flirting with them. ( I identify as straight) and over time these thoughts and self destructive behavior hasn’t bothered me and now they feel apart of me I know apart of it is ocd but also it’s me like me willingly looking at women and me wanting to have sexual thoughts or feel aroused and in reality if I never had ocd I would never think this way I could live without women and never sleeping with them I do have a bf and I love him and am attracted to him rn thought bc of what happened last night with a women it’s hard to feel that can anyone relate?

I need too know that I'm not insane, really. I am 16 and for the past two weeks, this has been completely ruining my health and happiness. I only recently came out as a lesbian like 3 months ago after a lot of confusion about my attraction since I used to think I liked men. At first, I felt so sure that I liked women, but lately, I've been having these unwanted thoughts about the possibility of liking men. I never used to feel this way, but now, every time I look at a man, my brain obsessively fixates on it. It forces me to imagine kissing him, loving him, things I don’t want, and then tries to convince me that I do. It’s painful. The thought of this fills me with fear and anxiety, leading to panic attacks and breakdowns. I don’t want these thoughts. I hate them with every fiber of my being, but I’m terrified that one day I’ll act on them and somehow like it. I used to think I liked men, but back then, I was in a very unhealthy space in a time of escapism and something deeply parasocial. I’ve only ever liked the attention and validation a man could give me, but these experiences are somehow treated as further proof that I’m "bisexual." I’ve never been in a real relationship with anyone, which makes my brain constantly challenge me—telling me, “You don’t even know what love feels like.” It won’t shut up. It keeps obsessively trying to make me prove that I’m a lesbian, testing my reactions and questioning my certainty. Is this normal?

I never read someone talk about this so I wanted to know if it applies to anyone as well. For context: I deal with ROCD and SOCD but I do identify as straight and am in a (happy) relationship with a man. What often triggers me is memories about childhood and adolescences about having the groinal toward nudity in porn or music videos. Because I can’t deny having watched other things than straight porn and experimenting with porn I simply can’t stop trying to figure out what that might have meant and if i deep down have actually a other sexual orientation than the one that I feel comfortable identifying with. I only hear people talking about random triggers but never the REAL memory of arousal to pornography and so on.
