Is this a common obsession?

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?

Is anyone here actually gay and has/had sexuality or religious ocd? I don't have it at all haha I'm a lesbian myself without socd or religious ocd but I'm just curious: what's it like and how did you deal with the whole "biggest fear coming true" thing?

I wouldn’t really say I have SO-OCD, but it manifests in some areas of my TOCD. Like if I see a woman for example my thoughts will go “what if I like her but as a man?” like my thoughts say I’m a straight man instead of a straight woman. And it’s really bothering me. If I see an attractive woman my brain will re-wire and imagine myself as a man looking at an attraction woman and it gets super uncomfortable that I have to like shake my head and say “no no no no no” multiple times to get the thought out. I know that counts as a compulsion but it’s hard to not do it because it’s so triggering. Now I don’t mind if I like women, however I’m really scared that I’m actually a straight man who likes women (or at least a bisexual man, considering I like men) and I hate it because I don’t want to be a man. Like I’ll think of my desired relationship as a woman dating a man but my OCD will switch it up to me being the man dating the woman, which is the opposite of what I want. I don’t want to be a man at all and I don’t want to date a woman, both of those are the opposite of my desires, but I’m still so scared. I’ll accept myself if I actually like women and am a bisexual woman, however I heard that being bisexual can mean being trans which scares me (for the record it was said in reddit by a sub which is mainly focused on a pseudoscientific phenomenon, that is still believed by the members to be true, so it’s definitely not a trustworthy statement, but my OCD will use anything to work against me) Does anyone here relate a little? 🥲
