It… might be

Not really

Could be. A lot of people with ASD are very sensitive to touch, and we often give special permissions to people we know well with regards to our boundaries. Case in point- my very complex relationship with pronouns rn.

Hmm

Could be . . . but many of those tendencies are contingent on other things. You can quite easily not want to be touched at all by some people or in some settings, but be quite happy to be touched under other conditions, or at some phases of your life more than others.
