Serious question: Are obsessions about being gay driven by homophobia?

Trying not to seek reassurance, but rather connect the dots on my OCD and possible reasons as to why I am the way I am. I have severe OCD (or at least I hope I do) mainly surrounding POCD. I've had symptoms of OCD the majority of my life but this theme has come up more recently. When I was a kid, and i'm talking 6-7, I was first exposed to some really gross adult content online. It was introduced to me by a friend of mine around the same age of me. I saw some really disgusting things that a 6-7 year old should definitely not see. This was not a one time occurrence, as I had been exposed to taboo topics online years to come after that, such as the same friend introducing me to Omegle... And i'm sure you can imagine how that went, theres a lot of genuinely disgusting human beings on there. Coming back to the reason for making this post; is it possible to early exposure to this content could be one of the reasons I struggle with POCD? It genuinely scares me to death because you hear that real p*dos dealt with simular situations when they were kids, so thats kind of making me feel that this could be more than OCD, and I could be a genuinely bad person. My POCD feels so real, that at times i'm fully convinced its not OCD. Sometimes I can't even distinguish the feelings of attraction between a younger person and an older person, except for the feeling of anxiety and fear. Its really hard to explain without going into detail, but it just feels so real. Some feedback on this would be great, thank you all.

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
