My T's have always been pretty open about these kinds of things that you are mentioning. Never caused me any problems to know that kind of information. They were never mysteries to me. It wasn't any big moment when they told me these things. It was just an accumulation of information over the years. It didn't detract from my therapy in any way, and I certainly didn't feel compelled to hunt out information about them. For me, it just kept them real.
