Nonconsensual sex is, of course, a crime. Consensual sexual activity is, for the most part, none of the state's business. While sodomy laws were once enforced across the nation, even between consenting adults in the privacy of their own home, the U.S. Supreme Court ruled those laws unconstitutional in 2003.
In that year, the U.S. Supreme Court heard Lawrence v. Texas. In that case, a man challenged his conviction in Texas for having sex with another man in the privacy of his own home, which violated a state anti-sodomy law. However, the U.S. Supreme Court ruled that law unconstitutional and unenforceable. In the wake of that decision by the U.S. Supreme Court, all anti-sodomy laws, as they apply to consenting adults, became unconstitutional and unenforceable.
As in other states, Montana's prohibited consensual sexual activities laws are limited to indecent exposure, prostitution, and pimping.
