Is this a common obsession?

So my ocd theme changed to sexual orientation ocd last December after I heard a popular video "hi, I'm Gibby" and I went like the Gibby sounds like "gay", then I started saying the phrase and over days, I started getting intrusive thoughts "I'm gay" .(I have had other ocd themes: (magical thinking ocd, symmetry ocd, health concern ocd, religious and spirituality ocd and harm ocd ever since I was 12, they just come and go)....I struggle with other conditions(ASD and bipolar disorder). I have never struggled with sexuality or questioned it because I have only liked males right from when I was in grade 1🥲...I still like them. SO-OCD is very frustrating because deep down I know I'm straight and there's no evidence I'm not but the intrusive thoughts and compulsions to get relief (the cycle) won't stop. I'm on fluoxetine(Prozac) and it did help my symptoms but lately I realised I'm more consumed with compulsions and idk but I think it's reducing the effects of the drugs?.. I see an attractive female and my mind goes like you found her attractive you must be gay or I want to go out and do sumn"what if you discover you like them or are gay" ...idk it's frustrating, very and I'm tired. I don't even get turned on by same sex or any😭that what even makes it more confusing.+ It's almost like I'm now hypervigilant when Watching videos or Instagram reels...it making me forget that finding someone physically attractive≠sexual attraction...idk if anyone gets me...(Rn my ocd themes are SO-OCD and religious and spirituality ocd) SO-OCD is frustrating, I'm tireddd...how can I never have struggled with sexuality for almost a decade and half but I'm having it now(it's started two months ago)...who has had/have this theme??

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?
