scared of thinking of other people PLEASE RESPOND

Background: I'm 17 about to be 18. I cheated on my boyfriend with this guy S( which I now cut contact with) months and months ago, I came clean to my boyfriend and he forgave me but that's when this all started. I'm not diagnosed with Ocd yet but jm seeing a local counselor. Now: In the past months I've been having thoughts like " what if I love S" "What if my boyfriend is just a friend to me" "I'd rather S did that * insert sexual thing or normal romantic thing*" " S wouldn't do that" "What if I secretly love S" "I love S" and I kept imagining scenarios with S to test how I'd react physically. These thoughts are there everyday for me 24/7, some days it's worse some it's better but I cry about them everyday because they build up and I just explode. I don't want to have them but they get worse and worse with time and I'm scared they reflect some kind of truth because of my past. I finished to have a crisis now, lasted at least 1 hour and I cried my heart out, my mind was like " I dont want anyone else to touch me like my boyfriend does" but then it said back " I love S" " I want S to do that" ecc ecc, got so bad I need to refocus during sex and I need to see my boyfriends face to be sure it's him because I'm scared S is gonna come into my mind and I'm gonna get turned on for him thing that scares me to death. I had the same with pedo like thoughts, for a while I had to avoid children because I was convinced I was a pedo. This comes and goes but the theme it's most in my mind it's this S theme around my relationship. I love my boyfriend and I don't want any of this, can someone please suggest me what to do?

any help is really welcomed and appreciated. I tend to hyper fixate on men outside of my relationship, they feel like crushes but I’m like 60% sure they’re meaningless dopamine rushes that happen with people I find interesting, friendship worthy, or physically appealing in some way. My hyperfixation recently shifted to a supervisor, not even an hour after meeting him :/ that’s fine, whatever, I can’t do much about it. I daydream and create like this drama romance in my head. Like good content for a movie or a book. Comparing it to that makes me feel less disloyal, and more understanding of why this might happen (I am a hopeless romantic, I adore stories). I’m home now and I was thinking of wearing a cuter shirt for work tomorrow because I went in an oversized hoodie today. This is a thought I had this morning before even meeting this man btw. But then my brain went to oh yeah I want to look attractive for this hyper fixation. It felt exciting to think that. I felt excited. Then the huge wave of dread hit me. I wanted to look good for another man? For a specific person? I can’t stop panicking I don’t know if this is normal, disloyal, a distortion, or what it is. I’m so confused. I felt happy when I got that thought. Maybe it was a dopamine hit or something I’m Colombian and we’re really big on looking our best 99.9% of the time. Even if it’s just to go to the gas station. I just feel so scared that I felt excitement over this one person. It’s extremely different for my boyfriend’s culture. Almost the opposite. I feel so disloyal and unworthy of my boyfriend. I doubt this was intrusive, it genuinely felt like me and I’ve had thoughts like that in the past. I just feel like a huge monster right now Please help :(

I need advice. I’ve had OCD in different forms since I was eight. I’ve been with my boyfriend for two years now. He has always been subtly anxious and jealous. He would say things like, “I find everyone but you ugly” or “I could never find anyone else attractive.” That stressed me out morally, especially since it’s our first relationship and I, of course, want to be good enough for him. It started around the three-month mark of our relationship. Now to the problem: When I see someone who is attractive or cute, it already begins. I start thinking—or rather, I don’t just think, I feel. I genuinely and naturally feel these emotions, like I find that person attractive, like I like them, like I want them. I even feel infatuated, like I want to be with them, spend time with them, be their partner, even sexual scenarios or feelings like I love them. These emotions feel so natural and real that I can’t tell the difference. With one person, I’ve had these feelings for over a year. But I only know most of these people by sight. It could be that I’ve fallen in love with the idea of them. That’s a big issue for me. It completely goes against my moral values. I don’t want this. For me, it would be terrible to have a crush on someone else, to like someone else, or to fall in love with another person. Or worse, to love someone else. Because I do love my partner, and I want a future with him. And I know the relationship wouldn’t survive if my fears came true. Even if he always tells me, ‘No, I wouldn’t break up with you,’ I couldn’t live with it myself. And the thing is, it’s not even such an unrealistic fear. It’s not like I’m afraid I want to kill someone or that I have feelings like that. No, this topic I’m dealing with involves real people. There are many people who suddenly fall for someone else, who develop a crush or even fall in love with another person. And I can’t reconcile that with myself. A year ago, I saw someone, and it hit me like a shock (I think in a negative way). Yes, he is attractive or cute. But in that moment, I felt so much fear, panic, and adrenaline because I felt and thought that I liked him more than my partner. When that happens, I start testing my feelings again. And of course, I feel exactly what I’m afraid of. I then constantly feel this pressure or burden, along with guilt. When I think about a scenario, or imagine the person, those feelings come immediately—followed by fear, panic, and guilt. Because of that, I avoid certain places, things, or even numbers because I’m afraid of being triggered. By now, I’m convinced these are my true feelings, because I just can’t imagine that OCD could produce such emotions, and for such a long time—sometimes over a year. I simply don’t want this. I just feel awful, like a monster. What should I do?
