" The more you love, the more you can love—and the more intensely you love. Nor is there any limit on how many you can love. If a person had time enough, he could love all of that majority who are decent and just. Masturbation is cheap, clean, convenient, and free of any possibility of wrongdoing—and you don’t have to go home in the cold. But it’s lonely. "

― Robert A. Heinlein , Time Enough for Love
