For myself, I see no difference between "I'd like to get to know your body better" and "I'd like to get to know your mind better."

I'm really interested in this conceptually. You'd be OK with someone you met who you might want to talk to asking to explore your body instead of having coffee and conversation? You'd be OK with someone asking you in a previously non-intimate context whether you'd like to be fucked?

I find that the question itself presumes a context about the availability of that option. There is no context in which a random stranger may touch me intimately. So the question itself is inappropriate.
