My T's boundaries are pretty loose. No showing up at her house, no calling just to chat, a few times a year she "unplugs" for a week, no physical violence towards anyone including myself in session, don't threaten her or her family .....When I ask about it she laughs and says she couldn't imagine me messing up her boundaries. She invited me to her yoga class though I don't have the courage to go yet....she sits on the floor with me sometimes but she broke her hip and had surgery and so it's not always comfortable for her to be on the floor. I get an embarrassing amount of physical affection from her though I always want more. I am really ticklish and when we are dealing with my inner child I sometimes get tickled. The other day at the end of the session she said "wow I really have to pee! Good thing you weren't tickling me!".
Now I have zero erotic transference just a strong playful mischievous streak...but I was like "that's an option? I didn't know that was an option". She smirked at me and said "well it probably wouldn't be therapeutic"..but no boundaries going up..so it's hard to find much she isn't OK with.
