imagining scenarios to check reslly makes me feel like i want it. can this be ocd? can ocd be this real?

I’ve been feeling the urge to avoid intimacy or purposefully engage (for reassurance that I won’t give into a compulsion) because of intrusive thoughts and fear that I’ll “check/test” my reactions. My OCD is making me so scared that I’ll purposefully think of a child and try to see if I like it. It’s so complicated but I guess I’m mentally checking if I would mentally check during intimacy. I’ve even envisioned myself checking and it’s making me so nauseous. I know it’s a compulsion like any other but the sound of “touching yourself to the thought of a child” sounds atrocious and vile. I’m terrified I’ll automatically start checking next time I am being intimate. I truly feel so worried. If anyone has gone through something similar, I’d appreciate hearing your experience. Or if anyone has any advice?

does it also happen to you that during exposure to erp you can imagine that act and scene in detail, and feel some confused excitement that leaves you stressed because it is hard to believe that it is part of OCD, it seems so real! When i can imagine it in detail and feel it like i can actually get arousel about it.

I really dont know if it is ocd anymore I dont want certain sexual things with my bf anymore that i used to like When i envision it with a girl it is so easy to envision and it feels like i want that , that will give me the satisfaction This feeling is making me really question if i am still into men , desire men sexually Is this still ocd , i really dont know anymore , as it is a feeling it is too real
