As far as the skin to skin tactile issues, have you considered that it may be an anxiety issue? I have GAD and sometimes I don't like how my skin feels when other parts of my body are touched and I realized that it was anxiety that created that feeling of wanting to crawl out of my skin as well. It may be worth looking into for you.

With the food tactile issues, I have an issue with peas. I cannot stand the feeling of the mushiness of the peas. My brother used to have issues with mashed potatoes as a kid but he grew out of his problem, I never have and I'm a senior now.
