physical touch

How do you deal with physical touch? I hate it, I have immense difficulty accepting it and often giving it too, the feeling of someone directly touching my skin is agonizing, apart from my mother and very specific people that I can tolerate longer and even like depending on the context. I had to do a lot of mental exercise to achieve the level of acceptance I have today. But for example, I couldn't have a romantic relationship, because I don't let the person touch me, and I wouldn't touch them much.
