OCD CUCK (Please HELP)

I've been having intrusive thoughts about cuckoldry. When I masturbate, without porn, images of my girl getting ###$ by someone else come into my head randomly. When I watch porn, I keep getting the reoccurring thoughts that the person getting ###$ is my girl, as in the pornstar is my girl and I'm jacking off to another man ######6 her. *mod edit* I've always been against cuckoldry and stuff, and pretty much never watched vids with more than one dude, I found cuck vids repulsive. But for the past two months, I've been having intrusive thoughts about this. Throughout the day I do compulsions to reassure myself that I'm not into cuckoldry and that I will never be into it. How can stop these thoughts and be my old self? Every time I get a good reassurance it goes away for anywhere from a few hours to a few days, but It comes back. I've always been repulsed by cuckoldry, don't even watch cuckold porn. How can I stop these thoughts, am I becoming a cuckold? I don't want to be a cuckold, I've always found it weird. These thoughts started when a friend called me a cuck as a joke/insult. Please Help and reassure if you can.

I think the best thing is to try and ignore the thoughts and not let them bother you. You know what you like, and what you don't. If you don't like a particular kink, then you don't.
