Second-degree sodomy is a felony charge, used in several state criminal codes, that covers oral or anal sexual contact with a person who cannot legally consent. The lack of consent comes from the other person’s age or from a mental or physical condition that prevents meaningful agreement, not from force or weapons. That distinction is what separates second-degree sodomy from first-degree, which targets violent offenders. A conviction brings prison time, mandatory sex offender registration, and a long list of consequences that outlast the sentence.
The Two Elements Prosecutors Must Prove
Every version of this charge rests on two things. The defendant engaged in what statutes call “deviate sexual intercourse” with another person, a term that generally covers oral or anal sexual contact and, in some states, extends to penetration with a finger or object done for sexual gratification.1Missouri Revisor of Statutes. Missouri Code 566.010 – Definitions And the other person did not or could not legally consent. Consent can be absent because of age, mental disability, intoxication, or physical helplessness.
The gender of either person does not matter. What matters is the type of contact and the circumstances that negate consent as a matter of law.
When Age Makes It Second-Degree Sodomy
The most common path to a second-degree sodomy charge is an age gap between the defendant and the other person. The specific numbers vary by state. Some statutes set the threshold at a defendant 18 or older with someone under 15. Others require a defendant at least 16 with someone between 12 and 15, provided the defendant is at least two years older. Even a single birthday can be the line between a felony and no crime at all.
The legal theory is the same in every state that uses this structure: a person below a certain age cannot consent as a matter of law, regardless of how willing they appeared. Courts look at birth dates. The defendant’s belief about the other person’s age is almost never a defense. Most states treat age-based sexual offenses as strict-liability on this point, so prosecutors do not need to prove the defendant knew. A genuine and even reasonable belief that a partner was old enough offers no protection in the vast majority of jurisdictions.
When Incapacity Makes It Second-Degree Sodomy
The charge also reaches cases where the other person was an adult but could not consent because of a mental or physical condition. Statutes break incapacity into three categories.
- Mental disability. A person with a cognitive impairment that prevents them from understanding the nature of sexual conduct. Older statutes use the term “mentally defective,” which legal scholars have noted is outdated. The core idea is that the disability makes it impossible for the person to grasp what they are agreeing to.
- Mental incapacitation. A person temporarily unable to understand or control their conduct because of a narcotic, intoxicant, or other substance given without their knowledge. This covers drugging scenarios, including drinks laced with sedatives.
- Physical helplessness. A person who is unconscious, asleep, or otherwise physically unable to communicate. The law treats a person in this state as categorically unable to agree.
Prosecutors prove incapacity with medical records, toxicology results, witness testimony about the person’s condition at the time, or expert evaluation of a disability. A defendant’s claim that the other person “seemed fine” or “didn’t say no” does not overcome evidence that they fell into one of these categories.
How It Differs From First-Degree Sodomy
In states that grade sodomy by degree, first-degree generally involves force, a deadly weapon, or the threat of serious physical harm. Second-degree does not require any of that. It is the charge used when consent is missing because of age or incapacity rather than violence. Grading matters because it drives the sentencing range, and the facts that push a case from one degree to another can shift a sentence by many years.
Penalties for a Conviction
Second-degree sodomy is a felony in every state that uses the charge, but the classification varies. Some states treat it as equivalent to a Class B felony with potential sentences up to 20 years. Others classify it as a Class D felony with a maximum of around seven years. The spread is wide, and the specific statute controls.
Fines can reach several thousand dollars, with mandatory court costs and surcharges on top. Some states add restitution to the victim. After prison, nearly every state imposes a period of supervised release or post-release supervision, commonly two to five years for felony sex offenses. During that time the person reports regularly to a supervising officer, lives under restrictions on travel and contact, and may be subject to electronic monitoring.
Sex Offender Registration Under SORNA
A conviction triggers mandatory registration under the federal Sex Offender Registration and Notification Act. SORNA sorts offenders into three tiers based on the offense itself, not an individual risk assessment. Tier I is the baseline. Tier II covers offenses punishable by more than a year that are comparable to sex trafficking, enticement of a minor, abusive sexual contact with a minor, or production of child pornography. Tier III covers the most serious offenses, including those comparable to aggravated sexual abuse and abusive sexual contact against a child under 13.2Office of the Law Revision Counsel. 34 USC 20911 – Relevant Definitions
Where a second-degree sodomy conviction lands depends on the facts. An offense involving a minor that carries more than a year of imprisonment will often fall in Tier II or Tier III, depending on the victim’s age and the specific conduct.
Tier I registration runs 15 years, with annual in-person verification. Tier II runs 25 years, with verification every six months. Tier III is lifetime, with verification every three months. A Tier I registrant who maintains a clean record for 10 years, completes any supervised release, and finishes a certified sex offender treatment program can cut the registration period by five years.3Office of the Law Revision Counsel. 34 USC 20915 – Duration of Registration Requirement
Some states add their own system on top of SORNA. A handful use risk-assessment levels that depend on individual likelihood of reoffending rather than conviction offense alone, which can affect what information is public and how often the registrant checks in.4Office of Sex Offender Sentencing, Monitoring, Apprehending, Registering, and Tracking.

What Registration Looks Like Day to Day
Registrants must keep law enforcement updated on home address, employment, and vehicle information, usually within a few days of any change. Jurisdictions maintain public websites that let anyone search registry information by zip code or geographic area.5GovInfo. 34 USC 20920 – Public Access to Sex Offender Information Through the Internet The site carries a warning that the information cannot be used to harass or commit crimes against registrants, but the fact of public searchability is itself one of the most far-reaching consequences of a conviction.
International travel also comes with rules. A registrant who plans to leave the United States must notify registry officials at least 21 days before departure and include the purpose, dates, itinerary, passport information, and contact information at the destination. That information goes to the U.S. Marshals Service’s National Sex Offender Targeting Center.6Office of Sex Offender Sentencing, Monitoring, Apprehending, Registering, and Tracking.

Collateral Consequences Beyond the Sentence
Prison, fines, and supervised release are often just the start.
Immigration
For non-citizens the stakes can be total. Federal immigration law treats “sexual abuse of a minor” as an aggravated felony.7Legal Information Institute. 8 USC 1101(a)(43) – Aggravated Felony An aggravated felony conviction makes a non-citizen deportable and blocks most forms of relief, including asylum and cancellation of removal. Even lawful permanent residents with decades of ties to the country face mandatory removal. Courts also examine whether the conviction qualifies as a “crime of violence” with a sentence of at least one year, and second-degree sodomy convictions routinely meet that threshold.8U.S. Citizenship and Immigration Services. Permanent Bars to Good Moral Character
Where You Can Live
Most states impose residency restrictions on registered sex offenders, barring them from living within a set distance of schools, daycare centers, parks, playgrounds, and sometimes churches. The buffer ranges from 500 to 2,000 feet depending on the state and the registrant’s classification. Many municipalities add their own restrictions on top, which can make finding housing in urban areas extremely difficult.
Jobs and Civil Rights
A felony sex offense disqualifies a person from a wide range of work. Positions involving children, healthcare, education, law enforcement, and government security clearances are effectively closed. Many states revoke professional licenses on conviction. The felony itself can suspend voting rights during incarceration or supervision in some states, and federal law prohibits convicted felons from possessing firearms.
How Long Prosecutors Have to File Charges
The window for charging second-degree sodomy depends on the state and on the victim’s age. For offenses involving minors, many states have extended or eliminated their statutes of limitations. A growing number allow prosecution at any time when the victim was a child, or they pause the clock until the victim reaches adulthood and then add years. For offenses involving adult victims who were incapacitated, shorter periods may apply, though felony sex offenses generally have longer windows than other crimes. At the federal level, there is no time limit on prosecuting sex crimes against minors.9Federal Bureau of Investigation. Statutes of Limitation in Sexual Assault Cases
Why the Specific State Statute Controls
Age thresholds, incapacity definitions, felony classifications, and penalty ranges all vary. One state’s second-degree sodomy is another state’s statutory rape or criminal sexual act, and the sentence can be more than double between neighboring states for conduct that reads the same on paper. Anyone facing this charge should have a criminal defense attorney who can work through the exact statute, the evidence, and the defenses available under that state’s law.
