Love consists in giving without getting in return; in giving what is not owed, what is not due the other. That’s why true love is never based, as associations for utility or pleasure are, on a fair exchange.
It is love rather than sexual lust or unbridled sexuality if, in addition to the need or want involved, there is also some impulse to give pleasure to the persons thus loved and not merely to use them for our own selfish pleasure.
Love can be unselfish, in the sense of being benevolent and generous, without being selfless.
