I've been meditating under his guidance for a couple years, and it's not that spiritual energy is turned into sexual energy, but vice versa. This is why you need to be celibate for awhile (often Taoists talked about the 100 days). Strong sexual energy is great news for those trying to reach higher levels, but you've got to conserve it.
Nearly a hundred years ago, Frank Channing Haddock had an entire chapter on "sex-energy" in one of his books and the importance of conserving it (though doesn't get into the esoteric stuff that Bill does.) This is nothing new, though the reason should not be blind adherance to some religious dogma, but rather correct cultivation.
As hard as it is to do, you just need to let it go. Don't wallow in your sexual thoughts and attach to them. Have them and let them go.
