Hocd and urges! Help

Hi All, I (22F) have been suffering from HOCD for the past three months. I am engaged to the man I want to be with. However, I can't kick OCD. I was recently aroused when looking at a model in lingerie. The lingerie was objectively sexy and I briefly thought about how she was posing for a man with her breasts out. Likewise, I thought about how sexy it would be if I wore that. But, now I'm terrified. If I can get these responses from the female body-not the male body-that must surely mean something. Likewise, I have trouble orgasming during sex and I don't always love making out. But, I really don't think I'm a lesbian? Long story short, I need help getting over this. I'm in college and I can barely study. All I do is worry. I can't even enjoy my engagement at this rate because I'm convinced I'm in denial. This sexual arousal gives me incredible amounts of anxiety, especially considering I have been turned on by stuff like this in the past. If anyone has any helpful words, please let me know. I am not seeking reassurance, but I felt this backstory was necessary to explain why this fear has been so potent. There may be some real attraction here, which terrifies me. I don't know what to do. I want to enjoy life and improve sex with my fiance but I'm feeling hopeless. If anyone has any words of advice, it would be deeply appreciated.

Hey guys. i’m a 14 year old female and i think i may be struggling from HOCD. My reason for this is because i really struggle setting aside thoughts about my sexual orientation. Growing up i always wanted to marry a man and have kids but up untill now there’s something in my head telling me that i don’t want to do that and i’m making it up. i have all kinds of intrusive thoughts about s€xual intercourse with girls and even just being in a relationship with a girl and they have become that common it’s like in my head that i’ve accepted it and my head is tricking me into the fact i like it, when in reality i don’t! there’s so much more to this but all i want to know is is this HOCD and i’m not in denial? pls it’s causing me so much distress, i’d appreciate any help! <3

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?
