Wow. I'm so sorry you have this struggle to deal with. You certainly haven't done anything wrong. That said, a therapist who is willing to get naked in front of a client seems to have some major boundary issues.

Now, you get the raw end of the deal because you can't have a proper T-patient relationship and you don't get a "real" friendship either.

I hope you will be willing to find another T who can help you process this awkward relationship and unfortunate position your T-friend has put you in.

Good luck.
