There have been a number of cases decided by the United States Supreme Court or by the courts of the various states regarding pornography, sexual activity and what consenting adults are allowed to do in the privacy of their homes (or sometimes, in other places). Note that under most laws, the term "sodomy" not only includes anal sex but oral sex and possibly certain actions with sex toys.
