SB 5.26.26
yas tv iha vai savarnam bharyam dvijo retah payayati kama-mohitas tam papa-krtam amutra retah-
kulyayam patayitva retah sampayayanti.
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
If a foolish member of the twice-born classes [brahmana, ksatriya and vaisya] forces his wife to drink his semen out of a lusty desire to keep her under control, he is put after death into the hell known as Lalabhaksa. There he is thrown into a flowing river of semen, which he is forced to drink.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
The practice of forcing one’s wife to drink one’s own semen is a black art practiced by extremely lusty persons. Those who practice this very abominable activity say that if a wife is forced to drink her husband’s semen, she remains very faithful to him. Generally only low-class men engage in this black art, but if a man born in a higher class does so, after death he is put into the hell known as Lalabhaksa. There he is immersed in the river known as Sukra-nadi and forced to drink semen.
