HOCD and more intrusive thoughts

I’m 25 and never ever thought this before my soocd relapse. I have a bf of 5 years. Never been a high libido kinda girl. Don’t get me wrong I do get turned on by my bf but not like every day you know? - That had always been in the back of my head, is this normal and ok? But my ocd has latched onto the most scariest what if EVER. My brain is now saying How do you know you won’t prefer to sleep and kiss girls if you haven’t tried it: and it’s that unknown that is scaring the shit out of me. I DONT AND NEVER HAVE wanted to sleep / kiss a girl. But now my intrusive thoughts is all I think about!!! I don’t want I don’t want I don’t want??? So why does my brain think BUT WHAT IF??? I know ocd thrives off uncertainty which is why I think this is happening? But I don’t wanna find out or work it out because all I want is to be with my bf and marry him!! Is this just the epitome of OCD?

Sorry long post. Anyone feel like now they’re just in extreme denial. Like when I was little I noticed guys more than girls in movies and was more drawn to them. I remember changing my mindset to switch that. 98%of my life has been straight until recently. I felt drawn to some guys but never thought of it sexually. Always had girl crushes dreams and porn. Now I watch porn and I feel like straight takes longer and then I go and watch gay porn and feel nothing until I tell myself it’s two attractive dudes and love is love and imagine physical sensations and then it hits like suddenly. Like I have to convince myself it’s alright. Then when I try again I can do all that but feel nothing and then straight porn works. Idk if it’s just getting a fix or the first time works with anything or what but it’s confusing. On top of that I’ve felt girl relationships including my wife maybe miss something and a guy maybe matches that feeling that but then I feel like I’d be missing something without a girl or my wife. Idk I’ve had some rough times in life with male figures in my life but idk. I feel like I have to convince myself more and more that I’m straight even more than the first time I dealt with this. Can someone relate? Please

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?
