Shadowking,
I can't tell you whether the thoughts will go away. In my experience, most of my OCD symptoms shift or wane over time. I used to wash my hands till they were bloody - I don't anymore, but new obsessions/compulsions take their place.
Are you taking any medication for the OCD?
You don't need to share this - but I would suggest you might want to talk to a counselor about your sexual history. How young were you when you were first exposed to pornography? Have you seen sexual acts performed as a child or been involved in sexual acts as a child? Some folks just really get into porn, but for others, there are things in the background which may be pushing the use of pornography, etc. and which when understood/processed can relieve some of the pressure/urge.
I'd talk to a counselor about the gay role playing. The fact that you engaged in this while at the same time disliking it seems indicative of something...but I don't know what.
