Thank you everyone for the replies.
No, my T has never asked me how I feel about touch by him or anyone, and we have never discussed boundaries.
I feel very conflicted. On one hand I feel very supported by my T, but on the other hand I'm worrying that something isn't right. I don't know if it's my history making me paranoid, or the things I read on here.
The only other thing I did not mention is he offered to add a third session a week for a very reduced rate, because I'm processing some difficult things right now. When I declined due to financial reasons, he offered it for free. I thanked him and said I would think about it. I don't know if that's a red flag?
My gut is telling me something seems off, just because I've worked with him for awhile and none of these things were ever issues. I felt like I had a very strong (safe) connection, but now I don't know.
