I don’t think asking her to share her clear boundaries with you is too personal. I followed your story for a while and I think this conversation with your new T could be very healthy. It’s acrually your right to know what her boundaries are. Just as you share personal vulnerable info with her, it’s her responsibility to let you know exactly what her boundaries are. That’s healthy for everyone! You could even share your own boundaries. I shared one with my T, I don’t like any kind of physical contact and if I’m going to be asked to do something new, I need to be told in advance. I feel better knowing she knows that, then it doesn’t have to come up when it’s too late!
