Sexual [or] Intimacy

"Do you love him?" "No, we're just friends." "They were 'intimate' with each other." "During lockdown, we were only allowed to visit a person if we had an 'intimate relationship' with them." I’ve been finding that there's a lot of confusion out there about the difference between intimacy and sex. The quotes above show how we often use love/intimacy as a stand-in to describe sexual/romantic relationships as though they are basically the same thing.
