TOCD but now Heterosexual OCD

So I am a lesbian who was having a lot of TOCD problems for a while. All of a sudden it turned into a thing about "what if you are feeling attraction to men and all your attraction to women was fake?" I can't imagine myself with a man and especially not sex, it makes me feel so sick. I can't stop questioning if those are true or not. I have been in a long term relationship for two years with my girlfriend, and I am 100% sure those feelings were real. I am so confused though now, I can't stand the thought of being straight or bi, I feel like I'm gonna cry. I am starting to check to make sure I don't feel attraction to any men around me and I still feel attraction to girls but it feels like I don't feel attracted to anyone. I can see a good looking man, but I never felt like I wanted a relationship with one, sexual or not. I only want to have sex with women but my mind keeps saying "what if you don't" and I'm so scared. I want to be a gay woman so bad but I am so scared I've just been lying to myself for 6 years about being a lesbian. I just wanna feel like myself again. I know this is OCD because I have OCD, and because all the questioning started very abruptly and it was triggered by the "what if" thought.

*hugs* HOCD/So-OCD doesn't know bounds even if you see it appearing mostly as people fearing being gay it can affect literally anyone of any walk of life.

Seeing as you can tell that this is definitely OCD. I would treat it as such and nip it in the butt as Snaga might say. Just say "f it" and don't care. Don't address it directly or try to prove yourself.

I just am so scared like what if my attraction to women was fake this whole time? I used to have a lot of anxiety and intrusive thoughts about my girlfriend coming out as a trans boy which was completely irrational because she is so feminine. I was so anxious because I couldn't stand the thought of being with a man. But now I've been so anxious like what if I do wanna be with one? It gives me so much discomfort to think about being with one but like now my attraction to women has subsided a lot and my sex drive has gone down since this OCD started and it's making me even more worried. My checking to see if I am attracted to men is getting worse and I hate it. I just want my attraction to go back to normal. I have a lot of trouble with just telling my thoughts to f off or just not caring. I don't know how to do it yet and I just wish I could go back to normal. This is consuming my entire life.

the more you feed into the thought, the stronger the thought get will get. the more space it will invade.

you mentioned Tocd previously - that didn't seem to stick so if you work on this theme, maybe this theme will not stick as well.

something that has helped me in the past is this line of thought: "well, if i am, i am. we will see how it all plays out." whether it meant serial killer or heroin addict. you are posting here because you know this is ocd. you are seeking reassurance which is a perfectly acceptable thing to want, but it won't help you out of this theme. challenge this. try and take back some of the power. laugh at it and remember a time where you didn't think this thought at all. easier said than done when consumed, i know, but it is my go-to method. challenge each thought. do not shove them away. the more you can withstand, the less impact they make.
