Pornography is a paid, professional performance by actors. It is a fantasy, it is not meant to be a rulebook and guidebook or a how to as a general rule. And it goes to show how poor our sex education is in this country that people are reduced to looking at an entertainment medium for information about the body.Still, porn provides somewhat a lesson to men and women who are trying to spice things up in the bedroom.
