The religious suspicion of sex is not confined to Christians. The leaders of other world religions have also expressed doubts about the propriety of carnal relations.

One example - from the Moslem faith - will suffice. After sexual intercourse or any discharge of semen (through nocturnal emission, masturbation, etc.) a Moslem is obliged to wash himself all over as thoroughly as he can. Until this is done he is in a state of ritual impurity and is not allowed to pray. It is extraordinary the lengths that the pious will go to in order to sanctify gross anti-sexuality.
