So is the blood of man and woman after successful coition. After a false coition, like prostitution, there is not newness but a certain disintegration.

But after coition, the actual chemical constitution of the blood is so changed, that usually sleep intervenes, to allow the time for chemical, biological readjustment through the whole system.
