§ 85
The thought that she has given her all to him is worked out still further in the irrational conclusion, which comes to some men’s minds, that there may be nothing left for himself for a future occasion. Therefore he will not take all this time, so as to leave a little for next time.
Possibly getting all of her at one stroke may be the root thought in Don Juanism. Jus primæ noctis may have originated from the idea that the noble lord should get all there was in the vicinity to get; and he was exercising his right to own and get everything in sight. The men who cool in their affections (or whose passions cool) immediately after the possession of the persons of their love objects may be inspired by exactly this egoistic-social thought, that there is a possession that may be acquired by means of one love episode, after which the woman has no more to give.
