>>43184728Probably you weren't loved/touched enough as a kid and now as an adult you dislike being touched. That's statistically what happens. People who grew up without human touch find touching people scary/uncomfortable whereas if their parents were super touchy with them, so too will they be.
It can in rare instances be the exact opposite though. Someone grew up without it can become touch starved and someone with too much of it can grow to really hate it.
