if the two actually care about one another

depends on what kind of intimacy

Whats a relationship?

Yup. So many couples in the world that don't base their relationship on sex or anything.

Yes

I don't think it can

no.

It’s very hard but it is possible. I don’t think it is possible forever though because you’ll begin to crave intimacy

Not really, assuming that the relationship is more than just a friendship.

at some point along with the relationship, it would happen so i guess no.
