From the sounds of it, chemistry/ attraction sounds important in order to have a relationships/ be intimate. What if I'm not attracted to anyone? As in, most people I know have had celebrity crushes, or at least had an "I'd tap that" moment for someone, even if they are strangers. I have never had that.

I'm fine with physically holding hands and hugging people if it's friendly, but if the touch entails anything more, it's...uncomfortable. Perhaps it's a fear of vulnerability? I don't know. That might be possible though.
