Can hocd can change your sexuality??

Is it normal for even straight people to question their sexuality at times? Before HOCD I was like I’m probably bi or whatever based on NOO CONCRETE EVIDENCE bc in real life I was only attracted to men and am in a stable relationship with a boy...but I got these random thoughts and they didn’t bother me as much that’s until HOCD hit :( and now I’m like NO IM STRAIGHT STOP ?

Can sexual orientation change?

So my hocd started over 2 years ago (I’m 20 yrs old now), when I was having a conversation with one of my friends and the thought popped into the back of my head what if the reason I don’t have a crush on any guys at my high school is because I’m a lesbian. Since then my sexuality has been on my mind 24/7 I didn’t know this was ocd until about a year ago but i’m only seeking treatment now. The hocd ramped up when I felt super aroused watching a movie with topless women, something that had never happened when watching men. Thing is I genuinely think I’m gay now, I’ve had this for so long that at first the thoughts disgusted me and caused me anxiety but now they don’t anymore. I saw so many tiktok videos about “pipelines” of certain interests gay people have that triggered me and read the comphet masterdoc which made me cry when I read it because I related to so much of it. When I was a child I was never boy crazy, I never really crushed on boys in my class (to be fair there were only 7) however I do remember writing a love note to a boy in first grade and having an immense celebrity crush on a disney channel star. I remember to certain things I did as a child that lead me to think I am gay and they keep replaying over and over in my head. Thing is over the past year I’ve had crushes on 3 guys I’ve met through dating apps. The last one I actually hung out with and I had my first kiss/makeout session 2 months ago. After that my hocd calmed down I enjoyed kissing him it felt euphoric the whole drive home just replaying our dates in my head. But now I can’t get the thought out of my head what if I didn’t like it enough? I didn’t get butterflies when we kissed (i do when I think back about it though) and didnt feel super aroused like that time I watched that movie. I feel nothing when I look at pictures and videos of men but with women I started getting this warm feeling in my chest which stressed me out even more. Idk what I am anymore and it is driving me insane. Does anyone relate?
