"There she lusted after her lovers, whose genitals were like those of donkeys and whose emission was like that of horses. So you longed for the lewdness of your youth, when in Egypt your bosom was caressed and your young breasts fondled." -- Ezekiel 23:20-21
So many of the Theologically Correct crowd worry about their kiddies leering at skin on their computer screens yet remain unaware of the naughty bits within the Bible. 
In their self-righteous fervor to turn the US into a Christian version of Iran, pro-censorship forces risk making it illegal to put these portions of the Bible on the web.  So these hapless busybodies don't realize that they're in danger of shitting in their own soup! 

Then Judah said to Onan, "Lie with your brother's wife and fulfill your duty to her as a brother-in-law to produce offspring for your brother."

But Onan knew that the offspring would not be his; so whenever he lay with his brother's wife, he spilled his semen on the ground to keep from producing offspring for his brother.  What he did was wicked in the LORD's sight; so he put him to death also. -- Genesis 38:8-10 (NIV)

"One day the older daughter said to the younger, 'Our father is old, and there is no man around here to lie with us, as is the custom all over the earth. Let's get our father to drink wine and then lie with him and preserve our family line through our father.'" -- Genesis 19:31-38 (NIV)
