Ayatollah Khomeini admonishes men-- on the use of the Libido:

A man can have sexual pleasure from a child as young as a baby. However, he should not penetrate; sodomising the child is OK. If the man penetrates and damages the child then he should be responsible for her subsistence all her life. This girl, however, does not count as one of his four permanent wives. The man will not be eligible to marry the girl's sister.  Ayatollah Khomeini It is better for a girl to marry in such a time when she would begin menstruation at her husband's house rather than her father's home. Any father marrying his daughter so young will have a permanent place in heaven.  Ayatollah Khomeini A man can have sex with animals such as sheeps, cows, camels and so on. However, he should kill the animal after he has his orgasm. He should not sell the meat to the people in his own village; however, selling the meat to the next door village should be fine.  Ayatollah Khomeini  (Quotes above are from Khomeini's book, Tahrirolvasyleh, vol. 4, Darol Elm, Gom, Iran, 1990, Source: Homa) If one commits the act of sodomy with a cow, an ewe, or a camel, their urine and their excrements become impure, and even their milk may no longer be consumed. The animal must then be killed and as quickly as possible and burned.  Ayatollah Khomeini  (From The Little Green Book: Sayings of Ayatollah Khomeini, Political, Phylosophica, Social and Religious, with a special introduction by Clive Irving, ISBN number0-553-14032-9, page 47 Source: Homa) Eleven things are impure: urine, excrement, sperm... non-Moslem men and women... and the sweat of an excrement-eating camel.  Ayatollah Khomeini  (From The Little Green Book, Source: Harwood's Mythology's Last Gods, 175)
