amative \AM-uh-tiv\, adjective:
Pertaining to or disposed to love, especially sexual love; full of love; amorous.
Theoretically, any given left-kisser should meet more right-kissers and, over an amative lifetime, or even good year in junior high, be subtly pressured to shift to the right in order to land a wet one -- or just avoid a broken nose. No?
