How can I overcome porn addiction? I have soocd and I'm addicted to lesbian porn

I am a girl's in my twenties. I got diagnosed with OCD last year. I have a boyfriend, sadly we're long distance right now. I've liked boys all my life. It's very difficult to sustain intimacy in a long distance relationship. Sometimes I have intimate calls with my boyfriend and it's nice. Other times, however, (and I am not proud of it) I do watch porn. I started watching porn when I was 16. I've tried to quit it many times but every couple of weeks I go back to it. And as everyone knows, one of the MANY problems with it is that your brain will always ask for more. More taboo things, more explicit things. I have a daddy kink. I've roleplayed with my boyfriend and watched porn of this kink. Now, the thing is that my brain keeps telling me that I won't orgasm unless I think of little girls being ab*sed. I've never looked for that on the internet, I never want to either. I am under EXTREME DISTRESS, because what my brain tells me feels SO REAL, and it's like my pleasure gets blocked and that contributes to me thinking my brain must be right. It wasn't like this before. I want to go back. I'm scared it will be like this forever now.

When I was single, I watched a lot of porn, specifically lesbian porn even though I’m straight. When I got into my current relationship I dwindled down and eventually stopped watching porn of any kind, around six or so months ago. I had a flare up recently that has caused me to question every part of myself including my sexuality and my identity, my relationship, and other things that are important and valued to me, and porn keeps popping up in all of these things. I feel like my porn usage was me cheating on my boyfriend, especially in the early parts of our relationship. I broke down to him last month about it and he said it was okay, that he forgives me, but I’m still hung up on it because I can’t shake the feeling that I’ve wronged him and that I’m a terrible person and that I need to leave him because of this. This is so excruciatingly painful. I don’t want to keep confessing over and over and over again, but I don’t want to be a dirty lying cheater, which I feel like I am.

I’ve been dealing with SOOCD for over a year now, and I have been having a very hard day today. I feel like I just need someone to talk too, my whole life I’ve always had girl crushes and always wanted to be romantic with women . Ever since I posted this picture on instagram and one person said I looked “zesty” in it , which is when I started obsessing about being gay . I feel like I put so much meaning to these thoughts where now I’m always checking how I feeling around men. I had a really bad porn addiction for a long time and bad anxiety which fucked up my sex drive. I feel like I doubt if I’m attracted to women when I know I am , but the doubt is so overbearing where I start to believe it . I never was interested in men sexually, and my ocd makes me feel like I like the thoughts even though I feel no pleasure out of it. I feel like I lost who I am as a person . It feels like I don’t even know what my sexuality is and it’s really upsetting to me . I meant this girl the other day and she is the most beautiful woman I’ve ever met and I just feel like ocd is getting in the way😭😭😭 please any advice or comments
