A sexual offender (also sex offender, sex abuser, or sexual abuser) is a person who has committed a sex crime. What constitutes a sex crime differs by culture and by legal jurisdiction. Most jurisdictions compile their laws into sections such as sexual trafficking and sexual assault. The majority of convicted sex offenders have convictions for crimes of a sexual nature. Some sex offenders have simply violated a law contained in a sexual category.
Some of the titles of crimes which usually result in a mandatory sex-offender classification include second prostitution conviction, sending or receiving obscene content in the form of SMS text messages (sexting), relationships between young adults and teenagers that have resulted in corruption of a minor, and any sexual contact made by the adult to the minor (child molestation). If sexual conduct occurs, unlawful sexual conduct involving a minor occurs.
Other serious offences are sexual assault, statutory rape, child sexual abuse, rape, sexual imposition, and pandering obscenity.
The term sexual predator is used pejoratively to describe a person seen as obtaining or trying to obtain sexual contact with another person in a metaphorically "predatory" manner. Analogous to how a predator hunts down its prey, so the sexual predator is thought to "hunt" for his or her sex partners. People who commit sex crimes, such as rape or child sexual abuse, are commonly referred to as sexual predators.
The term "sexual predator" is often considered distinct from "sex offender." Many U.S. states also see these differences legally. A sexual offender is a person who has committed a sexual offense. A sexual predator is often used to refer to a person who habitually seeks out sexual situations that are deemed exploitative. However, in some states, the term "sexual predator" is applied to anyone who has been convicted of certain crimes, regardless of whether or not there is a history of similar behavior.
