I "lucked" out with my first T who turned out to be a CSA survivor himself which he didn't reveal until after a few months. I have to wonder if some sex therapists and CSA specialists get into it because of their own background which leads to a desire to help others overcome it too. Maybe it's more common among them than you'd think?
But it was great for me once I knew that and let me really open up. He just understood things like "why I kept going back" without me having to "explain" it.
At times though it almost seemed mutual therapy because he still had issues/triggers as well which he was fully open about and admitted, and of course that was fully understandable. So I suppose we kind of helped each other in a way, although he helped me much more and looking back I feel it was money well spent.
Unfortunately I got transferred and never found another T as good as him... still looking
