I have avoided being touched as long as I remember by myself and by my parent's stories. Even as a baby I didn't like to be hugged or held or whatever else. Well, I have an Asperger's diagnosis, that may be the only point of it.
Just today I thought of it- I wished a colleague a happy birthday and shook her hand like I always do in that case- with everyone. I saw that she was ready to get hugged by me- it's this special little gesture people make when wanting to hug or being hugged... But I just couldn't do it. I am able to bear getting hugged by whoever if it is unavoidable without being really rude- but it is really a huge overcoming to do it myself because I really really hate it. But when I avoid it and see the other person is disappointed... Well, that's not a bit better... But I just can't help myself... I can't bear and if I do nevertheless, I'm totally overstrung after it, for hours.
If someone touches me from behind it may happen that I instinctively hit him... Yeah, not a good thing, I know. Not knock him/her down but just hit.
In the past I explained it to others by the rapings and the being-restrained-related things that happened in my childhood. But I don't know if that's really the point of it or if I'm like that by nature.
I can accept to be hugged or hug my partner. It isn't necessary for me but I can do it without any problem. But he's the only person (not he alone but all partners I had since now). But even with him I couldn't fall asleep while being touched or hugged by him or whoever else.
It's not that my mind, hormones- whatever wouldn't want some of those totally normal touch- related things people like to do... It's just that my body doesn't feel it the way it should- it's just far too much.
I can enjoy the very small things with very special persons though-persons to whom I have an inner connection (of which they often don't know themselves)- a short 'meeting' of hands when giving or taking something from someone I like. It can feel very warm, energy-rich. Of course the other person never knows what it means to me- it is something so small that it is never noticed conciously.
