"No such thing. Permissible, but not obligatory."
"But it was assumed. As a matter of course. Anyway ... well, when that girl started making passes at you, I thought you could have just as much fun, or even more—she's charming; a real darling, isn't she?—without pairing with me, and then I had to open my big mouth and be the one to keep you from playing games with anyone except me, and I certainly am not going to let you suffer...."
"Bunk!" Garlock snorted. "Sheer flapdoodle! Pure psychological prop-wash, started and maintained by men who are either too weak to direct and control their drives or who haven't any real work to occupy their minds. It applies to many men, of course, possibly to most. It does not, however, apply to all, and, it lacks one whole hell of a lot of applying to me. Does that make you feel better?"
"Oh, it does ... it does. Thanks, Clee. You know, I like you, a lot."
"Do you? Kiss me."
She did so.
"See?"
"You tricked me!"
"I did not. I want you to see the truth and face it. Your idealism is admirable, permanent, and shatter-proof; but your starry-eyed schoolgirl's mawkishness is none of the three. You'll have to grow up, some day. In my opinion, forcing yourself to give up one of your hardest-held ideals—virginity—merely because of the utter bilge that those idiot head-shrinkers stuffed you with, is sheer, plain idiocy. I suppose that makes you like me even less, but I'm laying it right on the line."
