This is totally normal for me too. I have actually asked my T to be mean to me and hit me. I told him I tend to dissociate whenever someone is nice to me. I can't deal with it. He knows I have also asked ex's to hit me rather than have them be stay mad at me.

Unfortunately, my T said he would never do that. He said even if it wasn't unethical, he would be scared of pushing it too far and he would do more harm than good. I was disappointed.

I would definitely talk about it. Your T will understand and maybe help you deal with the feelings. Mine tried, but I still feel the same way. Good luck to you.
