Help

I have had bits of OCD and anxiety as long as I can remember but never in this way. I am in a 3+ year relationship with my now fiance. About 8-9 months ago I started heavily doubting our relationship.. doubting his love for and intentions with me and that we'd inevitably split up. That turned into me questioning my love for him. Questioning if my amount of sexual desire was "normal", if it's "normal" to find other men attractive if youre with the "right" one and that would go in and on. Then came the SO-OCD. These worries, fears, and doubts made me questioning EVER bit of my sexuality and that being the reason why I've felt a lack of contentment in my very healthy, stable, consistent relationship. I feel as though this is my body going full on protector mode!! I've had my share of trauma growing up and in adult relationships that have left me with tons of relational wounds and then pile on a lifetime of fantasizing about what it would be like to find "the one" (thanks Hollywood and social media lol). All of this to wonder if anyone can relate to all of this and how you've been working through layered traumas and OCD

I think I've struggled with OCD all my life. I struggle with intrusive thoughts alot and recently I just broke down and fell into a spiral I can't get out of. I found out about relationship OCD and sexual orientation OCD and think I may have those. I had an intrusive thought a few months ago that what if i didn't love my fiance anymore and since then I can't shake the idea. Just the day before I told him how much I wanted him to be my husband and up until that point I didn't question my love for him. I don't understand how things can just shake me like that quickly. I know I love him deep down and anytime I get those feelings back my brain is like "you sure about that?" A week later I had a thought about what if I've been a lesbian this whole time and that I'll marry my fiance only to come out as a lesbian in the future. I've always been ok with being Bi, I considered myself 10-20% into women and 80-90% into men. I always had crushes on men and dreamt of finding the man for me one day. I also find women nice to look at but I don't know if it's admiration or actual sexual attraction. Either way I was find with identifying this way but now I'm so stressed that I've actually just wanted to be a lesbian this whole time and that I'm in denail and closeted. These thoughts are debilitating and now I can't look at women without being stressed or getting aroused.

Let me start by saying that I am not diagnosed but I suspect I have OCD. I came out as a lesbian girl 6 years ago but lately I have very often intrusive sexual thoughts about men. These thoughts make me feel disgusted, annoyed, anxious and uncomfortable but I can't help but check every time I can whether I'm attracted or not. I don't want to get married to a man, I don't want to have sex with men or even have any kind of relationship but at the slightest trigger I start to think I'm hiding something. I know everyone has noticed that I'm slowly shutting down, I'm no longer the same but I can't say what's going on in my head. Could it be OCD? and how do I stop thinking about it?
