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

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’ve been struggling with HOCD for years, and it started with an intrusive thought about being gay when I was younger. It came up at age 12 and ever since, I’ve been trapped in a cycle of doubt and anxiety. I obsess over whether or not I’m secretly gay, even though I don’t feel that way at all. What makes it worse is the fear that I might have internalized homophobia, and that’s why I’m having these obsessive thoughts. I worry that my anxiety is a sign that I’m repressing something or rejecting part of myself. It feels like my mind keeps repeating the same question—am I gay?—and no matter how much reassurance I get, the fear doesn’t go away. I used to pray for my family members, fearing that if I didn’t, something bad would happen to them, and now it feels like I have to control these thoughts, or something will go wrong. For a while, it was quieter, but a week ago, the thoughts spiraled up again, and now the anxiety feels overwhelming again. It’s exhausting, and I don’t know how to break free from this constant loop of doubt. Has anyone dealt with the fear of internalized homophobia alongside HOCD? How do you manage the anxiety that comes with it?

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?
