Mental compulsions

I haven’t started ERP yet. But just curious from others who have, How do you sit with compulsions when they’re mental compulsions? Or just “let them pass”? It seems it’s going to be impossible since none of my compulsions are physical/tangible 😓

My NOCD therapist (who has been awesome) and I are both struggling to identify ways in which I can practice exposure therapy while in-session, because the vast majority of my OCD symptoms are mental compulsions. For example: indecision and inability to commit to a choice; seeking reassurance on decisions from friends and family; mental review of things that have just happened / social situations; over-thinking and catastrophizing. I also have some other hallmark symptoms (contamination fears, moral scrupulosity, etc) but those tend to be inconsistent too. It’s hard to really practice these during my sessions because so many are in the moment and fleeting. By the time I join my session they are no longer active. How can we establish exposure responses during my sessions, if most of my OCD involves mental rumination and overthinking patterns/thought loops that only occur “in the moments - rather than specific or consistent compulsions (such as hand washing)?

I have just recently realized that I had SO OCD. This began whenever I was watching porn and had an intrusive thought about the guy in the porn. It was more minor at first, it was a majority of what I was thinking about throughout the day but it didn’t feel as distressing at first. If I had downtime to think about it, it would affect me but if I was just going about my day I wouldn’t notice it. I began going through the compulsions of checking myself. This lasted for a while until another obsession occurred. Then it seemed as if my SO OCD took a step back. I would have flare ups but they would seem to pass. Recently, I had a very bad night of constant compulsions and looking at pictures and imagining things to check myself. After that night it was very distressing, it affected me to the point where people around me began to notice and ask me if I was okay. One of the big reasons I was so upset was my girlfriend, we have been together for over 3 years and I want to spend the rest of my life with her. I was thinking “Oh my god, if I am gay I can never be with her.” I would sit and cry about it thinking I would lose her and that might life would change because I was gay. I finally had enough and talked to her and my parents. We did some research and I was so shocked to find out that I had a form of OCD, it was like a weight being lifted off my shoulders just knowing that other people have been where I am and that I’m not gay. However, I may have naively expected the compulsions and obsessive thoughts to go away now that I knew I had an actual problem. But I found that the compulsions and thoughts were still there and I was going to put some effort into getting better. I have researched and now know what to do when experiencing intrusive thoughts, yet I still have been performing the compulsions which is just feeding into the OCD. I find myself having intrusive thoughts and then start performing compulsions to see if they are true. What really bothers me is when I have an intrusive thought that tells me that I do like something. But when I think about it I have no desire to pursue those thoughts. However when I feed into the compulsions they just seem to feed into each other. It is like my OCD ignores all the things that I know I like and goes straight to panic mode. I am also trying to do ERP and am going to start doing my best to get better. Does anyone have any tips for not performing the compulsions no matter how anxious you are feeling and no matter how real the intrusive thoughts seem to feel?
