Erp just does not feel right (advice needed)

I hate that we have to suffer with sexual orientation OCD. Heck in the way, way past I was aroused by Lesbian porn but it never made me doubt my heterosexuality. But now with this OCD subject and the constant mental rituals ocd tells me that because of what I did in the past it means I’m a lesbian and I just haven’t realized it yet. And during ERP when the behavioral specialist tell me to imagine that the thoughts might be true (that’s what you have to do in ERP) it terrifies me and makes me so so sick. I just don’t want it to be true. I’ve always dreamed of having a husband, even now in moments like these I wish he was here to hold me now and tell me everything will be ok...

*EXPLICIT!!!!* Is it normal to completely loose your identity with HOCD? There's no "deep down I know I'm straight." I feel completely gay. I really think I am a lesbian in denial. I want my identity back. I've asked this before, but with ERP am I supposed to tell myself that I am gay? I don't know how else to except it. It's the only way that doesn't feel like I'm lying to myself now. It's extremely upsetting because I really don't want this to be my reality. My dad said that if I am a lesbian than I still get to choose who I'm with, but if I am then there's no reason not to be with a woman even if I don't want to be. I have to. If I'm a lesbian and I stay with my boyfriend then I'm just in denial and lying to myself and him right? I have to put myself in a box, I'm not capable of breaking societal standards for some reason as in if I'm a lesbian then I can only date women. My parents keep telling me that they don't think I'm gay, but I can do whatever. I think I'm starting to convince myself that this actually what I want. Hopefully just so I can get over the pain. I don't know anymore. I don't know how I let this turn into an actual identity crisis. It doesn't help that I have ROCD too. I think I'm going to go on the SSRI I was prescribed even though it had bad reviews. I've had OCD since I was like six years old, with multiple different things, but I keep thinking with this one what if it's different? *TMI* *TMI* *TMI* *TMI* I've watched lesbian porn in the past and have finished to it multiple times and for a while that was my go to, then I stopped watching porn altogether. I didn't have any emotional connection to it, but it worked. What if I didn't have an emotional connection because I didn't let myself? I had a fantasy about myself in a lesbian porn once, but again, back then I didn't think of it as something I really wanted in reality, infact it was testing, but I stayed aroused. I know I had fantasies about guys my whole life, but now I feel like I'm making them up. At the beginning of this I remember testing myself thinking about a girl and then switching to a boy to see if I would stay aroused, and I'd completely loose arousal with the boy. There was a lot of anxiety around this so I don't know if that's why or if it's because I'm actually gay. I really really really do not want to be a lesbian, but I read about another on quora that said she really didn't want to be gay and another girl answered by saying that she didn't want to be at first either and that in the beginning she wasn't even able to say the word "lesbian" and that she was extremely depressed in the beginning, but now she's happy. I don't want that. I don't even want to be happy and gay.

My initial thoughts are not as scary bc I’ve been doing erp. For example, when an initial thought comes across I don’t go into panic mode, instead when the thought comes across I tell myself “maybe yes maybe no” and I feel better. But the thing that is getting to me is that the next thought is usually “did you just suppress a gay thought” and that makes me go into panic mode. And I feel bad because I’m like damn if I am suppressing these thoughts that would be sad like why cant i just decide on one so that I could be happy. You know? And I didn’t have these thoughts before. It’s so annoying because I constantly feel like what if I’m in denial. And it makes me question whether I’m happy with or attracted to my boyfriend. I want to be happy so I’m like do I leave him and maybe date women, but then Im like oh no i don’t want to do that I want to be with him and be happy with him. Anyone going through something similar?
