It's hard and for someone like me with massive trust issues, I test them ALOT. I felt bad for my T after a while because I was doing it to him every single session for many months. He needed to reassure me that it was ok and he was trust worthy. I'm in over a year now and I still have trouble with it in some areas. Heck, I've known my best friend for 6 years and I still don't fully trust her.
