Sodomy is a legal term that historically referred to anal intercourse, oral intercourse, and sexual contact with an animal. The word still appears in criminal codes, court opinions, and military regulations, but its reach is far narrower than it once was. Since the Supreme Court’s 2003 decision in Lawrence v. Texas, consensual sodomy between adults is no longer a crime anywhere in the United States. The term now matters mainly in cases involving force, minors, bestiality, military prosecutions, and immigration consequences.
What Sodomy Means in the Law
Older sodomy statutes targeted specific physical acts rather than specific people. The core legal meaning covered anal and oral intercourse between two individuals, regardless of gender, along with sexual contact with an animal. Many statutes avoided anatomical language entirely, using phrases like “crimes against nature” or “buggery” to sweep in any sexual act a legislature considered deviant. That vagueness gave prosecutors wide latitude to charge conduct falling outside penile-vaginal intercourse.
The clearest formal definition appeared in the Uniform Code of Military Justice. Under the version of Article 125 in effect through 2013, sodomy meant “unnatural carnal copulation with another person of the same or opposite sex or with an animal,” and even the slightest penetration completed the offense.1Office of the Law Revision Counsel. 10 USC 925 – Art. 125. Sodomy That language applied equally to married couples, heterosexual partners, and same-sex partners. Consent was irrelevant. If the act fit the definition, it was chargeable.
State statutes largely mirrored this approach. Some criminalized the acts only between same-sex partners; others applied to everyone. The common thread was a focus on the mechanics of the act rather than on whether anyone was harmed.
Lawrence v. Texas and Why Consensual Sodomy Is No Longer a Crime
The 2003 case Lawrence v. Texas, 539 U.S. 558, is the reason consensual sodomy is no longer prosecutable anywhere in the country. Two men were arrested in a private home after police found them engaged in a consensual sexual act. Texas law at the time criminalized “deviate sexual intercourse” between individuals of the same sex as a Class C misdemeanor carrying a maximum fine of $500.2Justia. Lawrence v. Texas The defendants challenged the law on constitutional grounds.
The Supreme Court ruled 6–3 that the statute violated the Due Process Clause of the Fourteenth Amendment. Justice Kennedy’s majority opinion held that “the liberty protected by the Constitution allows homosexual persons the right to choose to enter upon relationships in the confines of their homes and their own private lives and still retain their dignity as free persons.”3Library of Congress. U.S. Reports: Lawrence et al. v. Texas, 539 U.S. 558 (2003) The government cannot use its police power to punish adults for private, consensual sexual conduct.
The decision explicitly overturned Bowers v. Hardwick (1986), where the Court had upheld a Georgia sodomy law and declared there was no constitutional right to engage in homosexual sodomy.2Justia. Lawrence v. Texas By reversing that precedent, Lawrence invalidated every remaining state law criminalizing consensual sodomy between adults.
When Sodomy Charges Still Apply
The Lawrence majority was careful to note that the ruling did not reach nonconsensual acts, sexual contact with minors, prostitution, or public sexual conduct. The dividing line is consent. Two adults in private are beyond the reach of criminal law. Everything else remains fully prosecutable, often under statutes that carry some of the harshest penalties in the criminal code.
Under 18 U.S.C. § 2241, aggravated sexual abuse committed by force or threat is punishable by any term of years up to life in prison. When the victim is a child, the mandatory minimum is 30 years, and a repeat offender faces a life sentence.4Office of the Law Revision Counsel. 18 USC 2241 – Aggravated Sexual Abuse A related federal statute, 18 U.S.C. § 2242, covers sexual abuse accomplished through threats or against someone incapable of consenting, and also carries a potential sentence of any term of years or life.5Office of the Law Revision Counsel. 18 U.S. Code 2242 – Sexual Abuse
State penalties vary but follow the same pattern: forced sexual acts are treated as first-degree felonies carrying long prison terms, with enhancements when the victim is underage, when the offender holds a position of authority, or when drugs or weapons are involved. Sexual contact with an animal also remains criminal in most jurisdictions.
State Laws Still on the Books
Roughly a dozen states still have sodomy laws sitting in their criminal codes despite Lawrence rendering them unenforceable against consenting adults. These are sometimes called “zombie laws” because they are technically on the books but carry no prosecutorial power. Legislatures leave them in place for different reasons, from political inertia to symbolic objection, and repealing them requires affirmative legislative action.
Where the laws remain, they function as historical artifacts. Any attempt to enforce one against private, consensual adult conduct would be immediately blocked under Lawrence. Laws targeting nonconsensual acts and sexual contact with minors are an entirely different matter and remain fully enforceable.
Sodomy Under Military Law
The military’s treatment of sodomy followed a different timeline than civilian law. For decades, Article 125 of the UCMJ criminalized all oral and anal intercourse, regardless of consent, gender, or marital status. The penalty was whatever a court-martial decided, which could include dishonorable discharge, forfeiture of pay, and years of confinement.1Office of the Law Revision Counsel. 10 USC 925 – Art. 125. Sodomy Service members were prosecuted for consensual private acts well after civilian courts had begun questioning the constitutionality of such laws.
Congress eventually acted. The National Defense Authorization Act for Fiscal Year 2014 repealed the blanket criminalization of consensual sodomy under Article 125, narrowing the offense to forcible sodomy and bestiality. Most sexual assault and abuse offenses were moved into Articles 120 through 120d, aligning military law more closely with civilian standards. Consensual sexual conduct between adults is no longer a standalone military offense, though nonconsensual acts remain subject to serious charges under the revised code.
Collateral Consequences of a Conviction
A conviction for a nonconsensual sexual offense almost always triggers mandatory sex offender registration. Under the federal Sex Offender Registration and Notification Act (SORNA), anyone convicted of a qualifying offense must register in every jurisdiction where they live, work, or attend school.6Office of the Law Revision Counsel. 34 USC 20913 – Registry Requirements for Sex Offenders Registration length depends on the tier of the offense, ranging from 15 years for the least severe category to lifetime registration with quarterly in-person verification for the most severe.7Office of Sex Offender Sentencing, Monitoring, Apprehending, Registering, and Tracking (SMART). SORNA In Person Registration Requirements Failing to comply is itself a crime that each state must punish with a maximum of more than one year in prison. The registry is publicly searchable, and most states restrict where registered offenders can live and work.
For noncitizens, the consequences can be even more severe than the criminal sentence. Federal immigration law classifies “rape or sexual abuse of a minor” as an aggravated felony.8Office of the Law Revision Counsel. 8 USC 1101 – Definitions That classification makes a noncitizen deportable and disqualifies them from nearly every form of relief that might otherwise prevent removal. Even offenses that do not reach the aggravated felony threshold can be classified as crimes involving moral turpitude, which create a conditional bar to the good moral character required for naturalization.9U.S. Citizenship and Immigration Services. Chapter 5 – Conditional Bars for Acts in Statutory Period A guilty plea that looks like a reasonable deal in criminal court can trigger automatic deportation with no judicial discretion to stop it.
