9. Sex, Homosexuality, and CircumcisionThe Bible's first commandment is to have sex and make babies. Just don't try to separate the two, as Onan did when he "spilled his seed on the ground." (God killed him for it.)
Semen, it seems, is very dirty to God. Whenever it comes out of a man it makes him unclean. Any clothing or skin that it touches is also unclean, as is any woman that may have been involved. The Bible even says that there should be a special place for men to go to cleanse themselves after they have wet dreams.
There are nine commandments about men with "running issues" out of their flesh. Such a man is unlcean, even when his issue stops. Any bed, chair, or saddle that he used is also unclean. Whoever touches the unclean bed becomes unclean. Whoever sits on anything that he sat on is unclean. And, of course, if you touch his flesh, or he touches you before he has washed his hands, or he spits on you, you become unclean. Any clay pots that he has touched must be broken, and any wooden bowls must be washed. When he finally cleansed of his issue, he must wait seven days and then wash his clothes and take a bath. On the eighth day he must bring two doves or two pigeons to a priest who will kill one for a sin offering and one for a burnt offering.
There are nineteen commandments about people whose nakedness you should not uncover, and another four about people (and animals) that you shouldn't lie carnally with. Commandments about lust and coveting are also covered, along with a few about homosexuality.
Male circumcision is God's "everlasting covenant." Even Jesus was circumcised when he was eight days old (Luke 2:21). But the Bible is inconsistent on the topic, with a clear difference between the Old and New Testaments. Three commandments in the Hebrew Scriptures require male circumcision; three in the New Testament imply that it is no longer necessary.
