Intimacy outside of marriage

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?

I’m struggling with something I’m afraid to even admit out loud. I’ve been in a long-term relationship with someone I love deeply. He’s kind, safe, and emotionally close to me — and we’ve built a life together. But I keep obsessing over the fact that I don’t feel much sexual attraction anymore. Or maybe… I never truly did? At the beginning, I felt butterflies, excitement, connection — and I assumed that meant I was also attracted to him physically. But now, after reading so much and reflecting more deeply, I’m starting to wonder if I ever truly felt sexual desire in the way I was “supposed to.” Maybe my feelings were more about emotional longing, comfort, and romantic closeness — but not sexual chemistry. And now I don’t know what that means. OCD makes it so much worse. It constantly tells me: – “If you really loved him, you’d want him.” – “You’re leading him on.” – “What if you’re lying to yourself?” – “If you try to fix this and fail, you’ll have to leave.” I feel stuck between wanting to fight for this relationship — and being terrified that trying will just prove it’s hopeless. Has anyone experienced something like this? Can OCD really make you question something so deeply personal? And how do you move forward when even trying feels terrifying? Any thoughts or support would mean the world right now.

Do you perhaps experience things like being so frustrated and numb because of how much your ocd drains you ? Then you are naturally caught up in a compulsion where you’re “physically testing” yourself to lets say something you watched years ago that is usually against your orientation?? If you know what I mean ? Even though you know you are (your own sexuality) and are in a very loving relationship and you really love your partner but does anyone experience this ?? And then they’re faced with more thoughts about how they’ve betrayed their partner and how their partner will leave and if you also struggle with scrupulosity ocd you feel like you’ve committed a huge sin and betrayed your faith ? Again I get all of this goes against values and that the human body may still react to things we naturally may be against but anyone still falls for the testing and then has this awful reaction afterwards? And does that really mean I betrayed my partner ?? Thank you so much for your time and I would really love your insights as this is something that popped up with me out of the blue …
