Anyone else suffer from the fear of being gay ?even thought you are certain you are not

Can sexual orientation ocd make you act on your fears and make you have same sex experiences ever and then after the experience realize that’s not what you are or want?

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?

Im a straight man and sometimes I make the mistake of compulsively getting on here. It’s gotten better but I slip sometimes. I feel like I’m alone in this and I even read on some OCD page that Women are more likely to suffer from this theme than Men. That just makes me feel like I’m in denial of some sort. I feel alone and feel like my intrusive thoughts are different. I know that’s what everyone who has ocd thinks, but I can’t help shake the feeling like what if I’m lying to myself or what if I have some underlying secret. I don’t want to be gay. I find I argue with myself in my head over and over and sometimes by repeating “I don’t want to be gay, I want to be straight” I’ll end up saying the opposite and that would scare me even though I know that It happened because I’m constantly fighting with OCD. Just feeling a bit down today. I had a sexual dream about an ex girlfriend and it felt great and I’m not scared by it. I find and want to be with Women romantically til forever.
