You are not alone with this. I too can’t bear to be touched. I can’t even stand someone standing too close behind me in a queue. My issues are due to CSA. I have improved a bit recently as I have allowed my new b/f to hug me. It’s by permission though & I dont like it, but try to put on a bit of a front. I feel like it’s something I have to endure, a bit like the CSA was! I feel that I’m weird & it does bother me. I talk about it a lot with my t, who sort of normalises it in my case.
