What Is a Federal Sex Crime?
A sex crime often includes conduct without consent or actions considered unlawful regardless of consent, including prostitution, sex trafficking, and indecent exposure. In most situations, sex crime allegations are handled by state courts.

Federal sex crimes carry uniquely high stakes compared to most other federal charges. People convicted of these offenses often face:
- Very long prison sentences, sometimes decades
- Mandatory minimum penalties for specific child exploitation or trafficking crimes
- Years of supervised release following incarceration
- Mandatory sex offender registration
- Rules restricting where a person may work or live
- Long-term harm to careers, relationships, and social standing
When Does a Sex Crime Become Federal?

- Using the mail or other interstate services to distribute illegal content or exchange communications linked to a sexual offense
- Offenses on federal property, covering places such as military bases, national parks, federal prisons, or federal buildings
- Crimes that involve federal interests, such as certain crimes against federal employees or offenses tied to federal programs

Types of Federal Sex Crimes We Defend in St. Petersburg, FL
Title 18 of the U.S. Code contains numerous federal sex crime statutes. Our St. Petersburg, FL federal sex crime lawyers defend them all, but the charges below appear most frequently:
Sexual Abuse and Aggravated Sexual Abuse
Federal law makes it a crime to commit sexual abuse or aggravated sexual abuse when force, threats, or individuals unable to consent are involved
- Sexual offenses carried out through violence or intimidation
- Cases in which a victim is impaired, unconscious, or incapable of consenting
- Sexual abuse of minors or vulnerable adults in certain federal settings
Child Sexual Exploitation and Child Pornography
Child exploitation laws at the federal level are among the strictest in the criminal code. Common federal allegations include:
- Sexual exploitation of children, commonly referred to as producing child pornography
- Distribution and receipt of child pornography, including online or electronic distribution methods
- Possession of child pornography, whether stored on digital devices or cloud accounts
- Exploiting a minor to generate explicit images or real-time video
Producing child pornography typically results in mandatory minimum penalties. Possession charges alone may still result in lengthy prison sentences, lifetime supervision, and mandatory sex offender registration.
Online Enticement and Internet-Based Offenses
Child pornography is not the only internet sex crime under Federal law. Frequently charged offenses include:
- Coercion and enticement of a minor through internet-based communication or messaging apps
- Traveling with intent to engage in illegal conduct with someone believed to be a minor
- Transmitting explicit content to a person believed to be a minor

- Coercing a person through threats or force to perform sexual acts in return for something of value
- Recruiting, transporting, housing, or controlling a person so they can be exploited for sexual purposes
- Any sexual activity involving a minor where something of value is exchanged, even if no force or threats are used

- Kidnapping tied to sexual offenses
- Transporting someone across state lines for illegal sexual activity
- Using threats, fraud, or force to move victims for exploitation
