I can tolerate some form of eye contact... I am not sure why, but I can look at some people in the eye for prolonged period of time, such as my wife, psychiatrist... myself. LOL. I usually like to look at other features as the eyes are usually the most intense part of the face that gives me many different mixed signals to me that I can't handle at the same time during a conversation with that person.
Tactile contact (touching, brushing next to me, stuff like that) - I am tolerable to an extent on that one. I will shake other people's hands if I allow them to... most of the times I don't do that. I also try my best to give a "hugshake" from time to time though I also am not nuts about it. It feels uncomfortable. I am deaf, so tapping me on my shoulder to call my attention is required in many circumstances, which is unfortunate for me because I have never come to terms of accepting that kind of contact. It is somewhat tolerable, but if someone repeately taps my shoulder for attention, I'd yell at the person to stop doing that. Some people just have no manners at all when it comes to that.
I hate it when people brush up next to me to be "over my shoulder" when I'm doing something, or trying to give other people some space and invading mine... I get visibly irritated and the person invading my space feels that I am disrespecting them for doing that! It gets annoying after a while, and it takes a lot to keep it under control.
