Tips?

I’ve had so many moments of clarity with my OCD that I love my boyfriend and I’m beyond willing to go through this to be better and be with him. in the back of mind I’ve in a way known I was at least somewhat sexually attracted to women (I’m a woman) since the start of the ocd it was always like “okay. Fine, but I don’t want to date a girl” I only just realized this after the ocd started, I never really argued with this. my ocd has always revolved around if I’m romantically interested in women and not men. I’ve done so many compulsions through this year and a half and 9 times out of 10 have come to the conclusion that I don’t want to be with a woman romantically. I always end up feeling like I know I love my boyfriend. But the doubts don’t stop about whether I want to spend my life with a woman instead, my heart literally breaks to think of not being with my bf and imagining him with someone else. I don’t want to be with a woman I know deep down somewhere underneath the anxiety that that’s not what I want. It doesn’t feel natural for me, unfulfilling. I want to tell my boyfriend about the possible sexual attraction to women (ik it’s still ocd related) but I’m scared that once I tell him, I’ll realize that I actually do want to be with women and not with him. Ugh I’ve spent hours today ruminating about this after being solid in my commitment with him for a little while, I’m stuck in this loop and idk how to get out right now

Specifically how can my fiance best support me without offering reassurance? I'm trying to encourage myself to grow and keep trying ERP, but I'm not sure how I can include my partner in a healthy way. I plan on talking to my therapist about it soon, but I wanted to hear thoughts from people who have been dealing with it themselves.

Last night I had a fucked up intrusive thought/urge about harming my partner and I'm spinning out today. I let them know I had an intrusive thought and was struggling with compulsions around it and future repercussions, but did not tell them exactly what the thought/urge was, which they accepted. Do y'all share details with your partners about harm ocd? How can we healthily ask for support from people we are having horrible thoughts about?
