This is completely consistent with the “binge trigger” concept: the idea that when the brain registers intense excitement (in the form of a neurochemical signal that something really valuable is about), it numbs itself temporarily in order to urge us to pursue more of it. The Daoists said too much climax “depletes the brain,” which is consistent with this concept, as the numbing is likely to be, in part, a product of reduced D2 (dopamine) receptors in the brain’s striatum.

Whatever the precise mechanism(s), the result can be that, instead of feeling satisfied after intense sexual arousal, we soon hungrily look around for further stimulation. In fact, the hotter the hook-up, the stronger the chaser. So be ready for it.
