Please help

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?

So pretty much I’ve been dealing with intrusive thoughts my entire life, I had no idea could’ve been symptom of OCD until maybe a year ago , I have this fear right now that I don’t actually love my fiancé and I’m not attracted to men. I am attracted to men. Let me be clear. I’m not attracted to females. I never have been and I never will be. But it’s one of the scariest thoughts I’ve ever had that I don’t actually care about the person that I would sacrifice anything for that I would do anything for. He’s pretty much the closest family that I have and I just wanna be with him for the rest of my life. A couple months ago was that I just didn’t care at all, and I didn’t have any feelings and everything that I felt was me being fake in that nothing was real. But I eventually got over that and the new thought is that I’m actually gay even though I know I’m not. And in the world we live in now where it’s be yourself be you if it comes across your mind. That’s the obvious truth. Be yourself… It’s kind of scary to think about. I just want it to leave me alone. I’m actually so scared that eventually I’ll believe it because some thoughts that I’ve learned were intrusive. I ended up starting to believe and it turned into a whole catastrophe for my life. I met this girl and she felt a certain way about her husband and then she told me that eventually I’ll feel that way and ever since then I just I haven’t gotten over this fear that I’m gonna end up feeling the same way she is. Also, I recently got over a few themes. I’m not ready to share, but I’m so proud that I got over those and I just I’m waiting for this one to leave me alone and it’s not and I’m starting to get really scared that it’s true and I don’t want it to be true. and just to be very clear I don’t care who you love what you love who you like what you identify as because you can in fact be yourself but this just doesn’t feel like me. I’m genuinely reaching out to try to get help for this because now it’s messing with our personal life. We’ve never argued so much in our entire relationship and now I realize that it’s mainly my fault because I’m detaching myself from all emotion just so that I can get over this thought I’m detaching myself from all intimacy and that’s even scarier because what if it’s not me detaching myself and it’s me just not being attracted that’s another thought I’ve hadI’ve gone all long enough so thanks.

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.
