Crime against nature
[3] For much of modern history, a "crime against nature" was understood by courts to be synonymous to "buggery", and to include anal sex (copulation per anum) and bestiality.This question was deemed sufficiently important that, in 1828, English law was explicitly amended to specify that proof of ejaculation was not necessary for convictions for buggery and rape.Specific acts included under this heading were typically deemed too detestable to list them explicitly, resulting in a number of vagueness-based legal challenges to corresponding statutes.The crime against nature statutes are, however, still used to criminalize sexual conduct involving minors, incest, public sex, prostitution and bestiality.Furthermore, in 2003, in Lawrence v. Texas, the US Supreme Court held that nonremunerative sex between consenting adults in private was protected by the Constitution and could not be criminalized under "crimes against nature" laws.
