I had an intrusive thought and urge to tell people I'm gay, but I'm not. I'm freaking out. Is that normal? Am I just in denial??

So I was enjoying some “me time” and had intrusive thoughts, but it felt like just for a second I liked it. Like I’m holding myself back from “enjoying” the thought. And the thoughts are related to things I was into when I was younger, but sometimes I feel like I might still like it even though 9/10 I wouldn’t give it a second thought. Is this common? Or is this just denial? Thanks

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 had a bad rumination spiral yesterday and went to bed hoping I’d start over in the morning. I was wrong. I had dreams about liking women and not being attracted to men anymore and my entire body has been in a state of anxiety since. I genuinely feel like I’m gay and just need to accept it. I have this urge to accept it. Maybe if I do I’ll get some sort of relief because this feeling is awful. I feel like my brain is telling me that I’ll get relief if I just accept it and come out. The intrusive thoughts don’t even seem to be around sexual images anymore, just to come out.
