I don't like being touched much either, even if I do know you. It's not that I'm afraid of where they've been, etc, but it makes me feel dirty and creepy. I especially hate anyone touching or kissing the top of my head. But if someone touches me really softly, I usually want to take steel wool and scrub my skin off. I don't even like the feeling of breath on my skin. I don't care if it's from a family member. It makes me want to rip my skin off. I was molested in daycare when I was 2, and it probably stems from that. But I can sympathize.
