Crime against nature
From The Art and Popular Culture Encyclopedia
Crime against nature is a legal term used in published cases in the United States since 1814 and normally defined as a form of sexual behavior that is not considered natural and is seen as a punishable offense in several U.S. states. In the broadest sense, a crime against nature could even include masturbation and unusual sexual positions, but these are not seen as such. Sexual practices that have historically been considered to be crimes against nature include anal sex, bestiality, homosexual acts, fellatio, cunnilingus and necrophilia. The term is sometimes also seen as a synonym for sodomy or buggery.
