It might change how a man and a woman discuss (or should discuss) how they might relieve their sense of isolation and poor social life.
Especially if, say, that man and woman always do things together, but one of them is starting to feel like they need a little bit of something else.
All they need to know is their own needs. Mine are not defined by my gender/sex, but by me; same with the person I'm talking to, same with you.
I'm not thinking about myself on the basis of what someone else thinks all people of my gender/sex do - that's irrelevant. Do you redefine your own needs based on what you read someone else thinks half the population does?
