Thank you everyone.
I appreciate everything everyone has said. Funny thing is, I told my wife when we were dating, told my GP when I started going to her to alleviate the surprise during a physical, no problem. I walk into shops and talk about clothes with the SA's without even blinking.

But for some reason I am drawing a blank when I think about how to tell the therapist. I'm not scared, not nervous, just am drawing a complete blank.
