Is it normal if you really value your relationship and You’re scared of cheating, if your brain makes you think you’re attracted to every other person you encounter because you’re scared of cheating

I know he’s not cheating on me. He’d never do that and, as hard as I try to tell myself “he’s proven already that he’s not” and show myself all the signs of commitment and dedication, I still have that fear. It’s eating at me and ruining my relationship. How do you guys get over this? If my brain were true he’d have been cheating on me for months in ways that aren’t even possible. It doesn’t make sense if I think about it logically but it seems like when I do, I create in my head more ways for it to be logically true. What is your advice? How can I stop self sabotaging?

I’m 25 and never ever thought this before my soocd relapse. I have a bf of 5 years. Never been a high libido kinda girl. Don’t get me wrong I do get turned on by my bf but not like every day you know? - That had always been in the back of my head, is this normal and ok? But my ocd has latched onto the most scariest what if EVER. My brain is now saying How do you know you won’t prefer to sleep and kiss girls if you haven’t tried it: and it’s that unknown that is scaring the shit out of me. I DONT AND NEVER HAVE wanted to sleep / kiss a girl. But now my intrusive thoughts is all I think about!!! I don’t want I don’t want I don’t want??? So why does my brain think BUT WHAT IF??? I know ocd thrives off uncertainty which is why I think this is happening? But I don’t wanna find out or work it out because all I want is to be with my bf and marry him!! Is this just the epitome of OCD?

I’ve been struggling with something that’s been really overwhelming, and I’m hoping to get some perspective from others here. I feel a lot of guilt about it, and I’m not sure if I’m alone in this experience. Lately, I’ve found myself daydreaming about romantic situations or getting caught up in ‘what if’ scenarios—where I wonder if I could develop feelings for someone else, or if someone develops feelings for me. The thing is, I’m in a relationship that I love, and I don’t want to act on these thoughts at all. What makes it even harder is that these thoughts often hyperfixate on one specific friend, and sometimes they feel entertaining or give me a dopamine rush. But then, of course, I feel even more guilty because it makes me feel like I’m betraying my boyfriend. These thoughts usually happen when I’m upset and looking for comfort, but then they morph into romantic scenarios, which makes me feel so disloyal. I’m constantly going back and forth between feeling curious or entertained by the thoughts and then feeling horrible for even allowing them to happen in the first place. I keep confessing these thoughts to my boyfriend, and he tries to be understanding. He’s just never been the type to daydream, so he doesn’t know if this is something other people experience or if it’s just me. I feel like such an awful girlfriend. Has anyone else dealt with something like this?
