I have an idea of why.

Many of the original settlers of the US were religious, and thought their country's church was corrupt. That led to a lot of religious people settling in colonial times. Another reason is in the 50s. After the Second World War and a possible third, family values were heavily emphasized in the US, one of which was going to church with your family. It was the kind of "wholesome" thing you did back then.
It's weird. It seems the US is one of the most prudish nations upfront, but I wouldn't doubt the US is in the top 5 for both watching and producing pornography in the world.
