struggling with possible ROCD

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?

I am a 21(female). I have only ever kissed one guy and it was horrible and I cried after. I stress about my sexuality constantly. I only want to be straight and know I want to end up with a man, but picturing it stressed me out and I am so scared to kiss a guy I think about it and get so stressed and cry immediately. I have severe intrusive thoughts about kissing everyone my teachers my best friends and it creeps me out and then I go down a rabbit hole of sexual orientation ocd! If anyone has any tips that might help that would be great. Again I don’t want or think I am gay but being so scared to be intimate with a man starts me down a spiral.

So I identify as a lesbian and I am in a committed relationship with a wonderful girl. But i’m stressing that I have crushes on boys I go to school with. I get anxious around them, which I think I mistake for excitement. I obsess over it in my head which confuses me a lot. Idk I also never think about them sexually or romantically but I think about them often which is scaring me. Any advice?
