a lot of people don't.
i've dated women who didn't want me to touch/kiss them ever outside of sex. it was weird. i can imagine that some people tolerate that behaviour and just have a partner who never touches them. i will say they all had massive control/anxiety issues in other areas of their life as well. I've also had partners who hated certain sex acts that seemed perfectly fun/normal to me.
a lot of people have very strict beliefs about the context in which touch should occur even with romantic partners. or consider touch to be 'dirty'
