I have OCD, and several months ago when I was first getting to know my new therapist I was talking about some of my sexual intrusive thoughts. He's not an OCD expert, and the first thing he asked me when I brought it up is if I could just be having fantasies and was ashamed of them. He went on to talk about some clients he had in the past who had similar "fantasies." 

I explained to him that they are intrusive, not fantasies, etc. And then we kind of dropped the topic. However, his comment really stuck with me and I'm afraid to bring the topic back up even though I have been really struggling with some of these thoughts. 

He is a really good therapist otherwise and I think we connect well. I just felt so misunderstood in that session and it's a huge fear that maybe these thoughts are actually things I enjoy that I don't know how to go about explaining it again to him without getting very anxious about him misunderstanding  :( 

Sorry about the rant! I know it's probably best to "just bring it up" with him, but if any one has any tips on how to navigate this convo or explain it more effectively (my brain sometimes freezes in sessions lol), I would appreciate that!
