I'd need to know what about CBT is affecting your sex drive.

When it comes to sexual obsessions, I just let myself experience whatever fantasy comes into my mind, while resisting unhealthy behavior; I sort of let my body react to it and don't avoid it, or do anything obsessive like tell myself it doesn't turn me on. I'm sure people can reply to this and come up with some extreme examples and things we shouldn't get turned on by, but in my experience if something turns you on, there's nothing you can do to get rid of it. Forcing yourself to not think of it or trying to not get turned on makes the anxiety and everything so much worse. No one has ever gotten hurt from my fantasies, and some of the more intense ones have calmed down overtime by doing this.

You want to focus on your behavior, so think of some of the things you do to try and get relief, and resist doing them. If you go into more specifics of what triggers you etc. I can give better advice.
