Why do I think this HOCD is my excuse and I am in denial? or am I really in denial

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

So I’ve talked to a couple of gay people and they all told me the same thing. They ALWAYS knew they liked guys and they have ever gotten aroused by a woman in their life. In fact they told me that they always found a woman’s body disgusting. Looking back in my life I’ve been attracted to girls for as long as I can remember even before puberty. All my fantasies were about girls and I can’t remember a time where I felt the same for a guy (because it never happened). At the end I can still get aroused by women and you can clearly see how much stupid this obsession about being gay is. Gay people can’t get instinctively aroused by a woman and like it. Groinal responses and sensations don’t mean anything because they simply do not bring joy or a feeling of desire. Instead they bring panic. I once got a groinal when “testing my reactions” and I was sitting there crying like my life is over. That’s not how genuine attraction works and no one has woken up one day feeling different and no one has been secretly gay and never noticed it and spent his whole life into women instead.
