You're only partly right, James.

In middle-school locker rooms - well, back when we actually had them - there was always one loudmouthed braggart who claimed to have it in with the ladies. He would tell stories about things like grabbing them by the crotches, shoving his tongue down their throats, and how much the ladies loved it. Other males in the locker room may have, in some sad way, believed him and thought "gee, I wish I could do that...", until a few more years of emotional growth provided more clarity regarding the nature of sexual relationships.

So that's where The Donald gets his locker room analogy: that's probably what he did, in middle school locker rooms.
