I think CE has a point here- even if our Ts went through the same things in their lives they might have felt it differently- no guarantee that they know what it was like for you. Being abused as a child- there are so many ways to overcome this and everyone should choose/find the way that suits them best. Plus telling your T about it IS part of the healing.
I'd never intentionally choose a T with the same life history- that's why I pick a 20 years older male. My T is not a blank slate T, he answers my Qs about his personal life, just facts though no feelings. I think he has lead a normal life and is quite happy now and I do wish him the best- selfishly, cause I wouldn't be able to do therapy (i.e. concentrate on myself for the 50 mins) if I thought he's dealing with stg in his life. I need my T to be OK.

BTW title was important for me when picking a T- I don't think MA are any worse than PhD- but there's a certain level of commitment in it and I didn't know anything about the Ts so I started with the ones with the highest qualifications and went from there. In my country any psychotherapist (MA/PhD) must undergo additional 5 years of individual/group therapy and supervision- so it is a bit different...
