SB Canto 2
SB 2.6.8, Purport:
The genitals and the pleasure of begetting counteract the distresses of family encumbrances. One would cease to generate altogether if there were not, by the grace of the Lord, a coating, a pleasure-giving substance, on the surface of the generative organs. This substance gives a pleasure so intense that it counteracts fully the distress of family encumbrances. A person is so captivated by this pleasure-giving substance that he is not satisfied by begetting a single child, but increases the number of children, with great risk in regard to maintaining them, simply for this pleasure-giving substance.
