Thoughts during intimacy

Anyone experience intrusive thoughts of their children during intimate moments? Have you done erp to this? I had one and continued slightly before running and needing to vomit now feel guilty anyone else experienced this?

What irritates me the most is that during intimacy with my husband, it happens that OCD puts an image and scene in my head, my sister or someone for whom my OCD is attached and it's literally as if that intimacy is happening with that person, and it seems real that I can and it's exciting! I'm working on ERP during that, but it's still hard to digest... I don't know if it's the same for you?

Last night my boyfriend and I were intimate, like most times that I’ve ever been intimate I couldn’t stay in the moment, thoughts racing through my mind causing me to be in my head rather than in the moment. EVENTUALLY, I was able to really be present and enjoy our time together, but it was once again fleeting. Afterwards I broke down and was crying, I had realized that OCD has ruined my intimate life from the very start. Of course my boyfriend was concerned so I opened up about what I was feeling. Well he started to explain that everyone gets distracted during sex and that it’s normal, so then I started thinking. What if I don’t even have OCD? What if I’m completely normal and just think I have OCD, I don’t have “episodes” 24/7, but I have them quite often. But maybe that’s just how the mind works?? My boyfriend said “you can’t control your thoughts, no one can” So does that mean I don’t have OCD? I’m spiraling and trying to understand it all. While we were intimate I had a realization that sex isn’t about what you’re thinking it’s about what you’re feeling, but I can’t stop thinking to actually be able to feel. Once I’m “distracted” I can’t get back into the moment, the thoughts pile and evolve and cycle and it’s never ending. I just don’t know, I know OCD can make you question if you even have OCD but what if I don’t have OCD and am just trying to convince myself I have OCD? HELP
