SB 3.14.22
athapi kamam etam te
prajatyai karavany alam
yatha mam natirocanti
muhurtam pratipalaya
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Even though it is not possible to repay you, I shall satisfy your sex desire immediately for the sake of begetting children. But you must wait for only a few seconds so that others may not reproach me.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The henpecked husband may not be able to repay his wife for all the benefits that he derives from her, but as for begetting children by fulfilling sexual desire, it is not at all difficult for any husband unless he is thoroughly impotent. This is a very easy task for a husband under normal conditions. In spite of Kasyapa’s being very eager, he requested her to wait for a few seconds so that others might not reproach him. He explains his position as follows.
