Anybody here ever obsess about being perceived as gay?

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 have been really battling with my SO OCD, and I’ve recently started to have a ton of wins!!! I’m really excited about it, but as I’ve noticed myself not engaging as much… different things have popped up. Now im obsessed with people’s perception on me, and them looking at me and thinking by how I walk, how I talk, what I wear, how I move… that I am gay? And am so convinced everyone thinks that and “knows something that I don’t”. Is that typical with OCD? If so, any ERP advice on how to overcome these thoughts?

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?
