What Is Criminal Sexual Conduct? Degrees, Penalties, and Consent

Criminal sexual conduct is a statutory framework many states use to cover sexual offenses on a single sliding scale, from unwanted touching through forced penetration. Rather than relying on the older crime of rape, these laws grade offenses by degree, use gender-neutral definitions, and tie each category of conduct to a specific penalty range. The federal criminal code uses parallel definitions and offers a reliable reference for the core terms and sentences, which most state statutes mirror or adapt.

Why States Replaced the Crime of Rape

Older codes defined rape narrowly: forced vaginal intercourse by a man against a woman. That left out oral and anal assault, penetration with objects, assaults against men, and coercive conduct that fell short of brute force. Starting in the 1970s, states began replacing those statutes with broader laws that removed gender-specific language, recognized multiple forms of penetration, and created separate categories for contact offenses that did not involve penetration.

Not every state uses the exact phrase “criminal sexual conduct.” Some label the same statutes “sexual assault,” “sexual abuse,” or “sexual battery.” The underlying structure is similar. When a charge is described as “CSC” followed by a degree number, you are looking at this modernized framework.

Sexual Act Versus Sexual Contact

The most important line in these statutes is between a sexual act (sometimes called sexual penetration) and sexual contact. Which side of that line the conduct falls on determines the degree and, ultimately, the penalty.

Under federal law, a sexual act includes penetration of the vagina or anus by a penis, however slight; oral contact with another person’s genitals or anus; and penetration of the genital or anal opening by a hand, finger, or any object when done with intent to abuse, harass, or sexually gratify.¹ “However slight” matters. Completion of the act is not required. State statutes typically track this approach, though the exact list of covered conduct varies.

Sexual contact is broader but less severe. Federal law defines it as intentionally touching the genitals, anus, groin, breast, inner thigh, or buttocks of another person, directly or through clothing, with intent to abuse, humiliate, or sexually arouse.¹ That captures groping and other unwanted touching below the level of penetration, and it reaches situations where the offender forces the victim to do the touching.

The Four Degrees

States that use a degree system typically organize criminal sexual conduct into four levels. First degree is the most serious, fourth degree the least. The numbering runs counter to intuition: a lower degree number means a harsher charge.

First degree generally involves penetration combined with an aggravating factor such as a weapon, serious injury, or a very young victim.
Second degree typically involves sexual contact (not penetration) with the same kinds of aggravating factors that would make a penetration offense first degree.
Third degree usually covers penetration without the aggravating factors present in first-degree cases.
Fourth degree covers sexual contact without the aggravating factors that would elevate a charge to second degree.

Two questions therefore govern every charge: what the offender physically did, and what circumstances surrounded it. A penetration offense with a weapon is treated very differently from a contact offense between adults with no aggravating factors, even though both sit under the same statutory umbrella.

What Elevates a Charge

The degree depends heavily on what else was happening beyond the sexual act itself. Statutes spell out specific aggravating circumstances, and the presence of even one can push a charge up a level.

Victim’s age. Offenses against young children carry the harshest consequences. Under federal law, a sexual act with a child can carry a mandatory minimum of 30 years or life. Most state statutes draw a hard line when the victim is under 13, with separate enhancements for victims under 16.²
Force or coercion. Physical force, threats of bodily harm, or intimidation to accomplish the act pushes the charge into a higher category.
Weapons. If the offender is armed or uses any object as a weapon, the charge escalates.
Injury. Physical injury or serious psychological harm adds another layer of severity.
Position of authority. Teachers, coaches, correctional officers, therapists, and family members who exploit a position of trust face elevated charges. Federal law separately addresses custodial situations: a sexual act with someone under the offender’s supervisory or disciplinary authority is a distinct crime carrying up to 15 years.³
Incapacitation. Administering drugs, alcohol, or other substances to leave the victim unable to resist is treated the same as physical force in most jurisdictions.

When Consent Is Not Legally Valid

Consent is the central issue in most sexual conduct cases. A person can only give legally valid consent if they do so freely, voluntarily, and with a clear understanding of what they are agreeing to. Silence or the absence of a “no” does not establish consent, and several circumstances make consent legally impossible regardless of what either party says.

A person who is unconscious, asleep, or too intoxicated to understand what is happening cannot consent. The question is not whether the person had been drinking, but whether they were so impaired they could not grasp the situation. Someone who cannot walk without help, cannot speak coherently, or keeps losing consciousness is well past the line.

Minors below the age of consent cannot legally agree to sexual activity. The specific age varies by state, ranging from 16 to 18 in most jurisdictions. Some states include close-in-age exceptions that reduce or eliminate penalties when both participants are minors near the same age, but the details differ sharply from one state to the next.

Consent obtained through threats, intimidation, or abuse of authority is also invalid. A prison guard who has sex with an inmate, a teacher who initiates contact with a student, an employer who conditions a job on sexual compliance: none of these produces legally valid consent, because the power imbalance makes free choice impossible.

Penalties and Sentencing

Penalties span an enormous range depending on the degree of the offense, the victim’s age, and the offender’s record. Federal sentencing offers a reference for the upper end.

Aggravated sexual abuse, the federal equivalent of a first-degree criminal sexual conduct charge, carries any term of years up to life. When the victim is a child, the mandatory minimum jumps to 30 years, and a second federal conviction for the same offense means an automatic life sentence.² Federal sexual abuse without the aggravating factors also carries up to life.⁴

Contact offenses draw shorter but still significant sentences. Abusive sexual contact accomplished through force or threats carries up to 10 years federally. The same conduct accomplished through incapacitation carries up to 3 years, and contact involving a minor or ward carries up to 2 years, unless the victim is under 12, in which case the maximum doubles.⁵

State penalties vary widely. Some states set mandatory minimums for first-degree offenses that exceed 25 years. Others leave judges broad discretion within wide ranges. Nearly all states impose substantial fines on top of prison time, and many require restitution to the victim. A first-degree conviction almost always means decades behind bars, and even a fourth-degree conviction can mean years of incarceration and a permanent criminal record.

Sex Offender Registration

Beyond prison time, anyone convicted of a qualifying sexual offense faces mandatory registration under the federal Sex Offender Registration and Notification Act. SORNA uses a tiered classification that sets how long you stay on the registry.

Tier I is a catch-all category for sex offenders who do not meet the criteria for Tier II or Tier III. Registration lasts 15 years.⁶
Tier II covers offenses punishable by more than one year that involve minors, including sex trafficking, enticement, child pornography production or distribution, and abusive sexual contact with a minor. Registration lasts 25 years.⁶
Tier III is the most serious category, covering conduct comparable to aggravated sexual abuse or sexual abuse, abusive sexual contact with a child under 13, and kidnapping of a minor. Registration is for life.⁷

Registered offenders must keep their information current in every jurisdiction where they live, work, or attend school. Any change of name, address, employment, or student status must be reported in person within three business days.⁸ Failing to register or update is a separate federal crime carrying up to 10 years.⁹

Time Limits for Bringing Charges

The window for filing criminal charges varies dramatically depending on the jurisdiction, the severity of the offense, and the age of the victim. There is no federal statute of limitations for sex crimes against minors. At the state level, at least 14 states have eliminated criminal time limits entirely for certain sexual offenses, and the trend continues toward longer or unlimited filing periods.¹⁰

Even in states that still impose limits, the clock often does not start immediately. Most states pause the limitations period while the victim is under 18, while the offender is out of state, or while the victim is mentally incapacitated. When new DNA evidence surfaces, some states allow the clock to restart. A defendant is generally subject to whichever limitations period was in effect when the alleged offense occurred, though legislatures can extend an unexpired deadline without violating constitutional protections against retroactive laws.¹⁰

Civil lawsuits operate on a separate timeline. Many states allow victims to file civil claims for damages well beyond the criminal deadline, and a growing number have eliminated civil filing deadlines for childhood sexual abuse cases entirely. A criminal acquittal does not block a civil lawsuit, because the civil standard of proof, more likely than not, is significantly lower than the criminal standard of proof beyond a reasonable doubt.
