How does Boy manifest his sexual attitude and energy?

Boy was a major philanderer. He manifested his desires in the form of all manner of sexual exploits:

I knew of his philandering, of course, for Boy could not keep anything to himself and used to justify his conduct to me late at night, when we had both had plenty of his whisky. “A man with my physical needs can’t be tied down to one woman—especially not a woman who doesn’t see sex as a partnership—who doesn’t give anything, who just lies there like a damned sandbag,” he would say, making agonized faces so that I would know how tortured he was.
