Anyone have any tips for quitting watching porn? Realized how bad and fucked up it is, and with OCD its just an unnecesarry habit

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.

Guys I just wanted to hang up and I was looking at pornography every time I was you know do it and I would get bombarded with thoughts I'd get overwhelmed with them like my mind is just constantly thinking of and it was just so hard infuriating I was looking at like anime pornography and Isaw one of the videos that looks familiar I watched it before but I remember they had like a underage anime character and then I clicked off it as soon as I saw them and my mom said oh you clicked it just so you can see that and what makes it worse is like pretty ejaculation already leaked out so now it feels like I did it i didn't even jerk off to you all I did was see the thumbnail and then I have thoughts like saying oh well might as well already get off to it when it wasnt the content I wanted to see I seen that the thumbnail before in the sight I just ignored it was focusing on the video I wanted to see for now I feel like i have to restart everything not only with the overwhelming thoughts but also my thoughts made it feel like I was actively seeking it like if I want my thought it was like oh you knew it was going to be there but u still click it anyway oh yes I had a feeling but as soon as I saw it I clicked off I don't know I'm just overthinking I guess and also like as soon as I saw it like my mind had a urge like might aswell get off to it finish it very hard I don't even remember how I climaxed I don't even know if I did it right but now I feel like I have to restart

TW: ZOCD, porn Before my ZOCD theme started, I would never find myself asking such questions... I'd never go through my past events, every possible things that could have happened, where now I feel guilty off - it didn't really bother me as much. I do remember experiencing some other themes for a shorter amount of time, but they didn't hit me as much as this one. And you know, I wasn't exactly "happy". I was bored, tired 24/7, I wanted my life to be more exciting, I wanted a struggle, which now sounds incredibly ridiculous. And guess what? I've got it. But I didn't want this type of struggle, who the hell would? But now I think of it, it was about to happen at some point as my problems with porn since I was 11, escalated to some really questionable things (always fictional, but it still affected me a lot). The final straw was when I consumed some fucked up fanfiction this April and the immense guilt and shame hit me few days after that. I've started questioning my whole being - why did I do that? Am I what I fear? What's wrong with me? Why was I so desensitised? Am I just now discovering the real me? How can I forgive myself? I've wasted so much time and energy on that, but back then it wasn't even that much of an issue for me. I was so blind. I should have realised that sooner, but late is better than never. I've been doing better mentally than say, three weeks ago but really... I just hate how much porn took away from me. And combined with my morbid curiousity, it led me into some dark places. I can only be glad that I've never saw the real thing.
