Actually this isn't inconsistent with the Taoist idea of ejaculation control. That's sex, without ejaculation, and therefore without loss of the yang energy. Apparently, the so-called Taoist methods include methods for the man to have orgasms without ejaculation; and in fact he can have multiple orgasms in this way, all in one blissful night.
