It gets very vague during the chapter about the transmutation of sexual energy into desire, but I did a bit of Google searching and found that there are people that will spell it out for you. It was probably fairly taboo to lay it out in blatant terms in 1937, but we're living in the future. Sex is more prevalent and less of a risque topic. Look into that specific topic and, if you have the willpower, it'll definitely boost you. You gotta release that energy somehow and doing it the quick and dirty way is a waste of potential.
You're absolutely right, but to anybody who's mature enough to understand the topic, they get it. There's a lot to be said for refocusing all of that energy towards a goal instead of partying.
It reminds me of this Longfellow quote:
"The heights by great men reached and kept were not attained by sudden flight, but they, while their companions slept, were toiling upward in the night."
