Lascivious behavior is sexual behavior or conduct that is considered crude and offensive, or contrary to local moral or other standards of appropriate behavior. In this sense, "lascivious" is similar in meaning to "lewd", "indecent", "lecherous", "unchaste", "licentious", "libidinous" or "lustful".
In American legal jargon, lascivious is a semi-technical term indicating immoral sexual actions and in certain cases, words or thoughts. It is often used in the legal description of criminal acts in which some sort of sexual activity is prohibited. The legal definition of the term varies greatly across jurisdictions, and has evolved significantly over time, reflective of current moral values as they relate to sexuality.
For example, in 1896, lascivious cohabitation referred to the now-archaic crime of living with a member of the opposite sex and having premarital sex with him or her. [1] In 2015, the laws of three states of the United States (Florida, Michigan and Mississippi) still considered "lascivious cohabitation" as a crime. [2] In 2016, Governor Rick Scott of Florida signed into law SB 0498 which no longer makes "lascivious cohabitation" a crime. [3] In 2023, Governor Gretchen Whitmer of Michigan signed into law SB 56 which no longer makes "lewd or lascivious cohabitation" a crime. [4]
In the 2000s, the term is often used as one of several adjectives to describe pornography, solicitation for prostitution, and indecent acts, such as the exposure of one's genitalia in public (e.g. indecent exposure).
In American law, mailing lascivious matter is prohibited thus:
Every obscene, lewd, lascivious, indecent, filthy or vile article, matter, thing, device, or substance ... [i]s declared to be nonmailable matter and shall not be conveyed in the mails or delivered from any post office or by any letter carrier. [5]
"Lewd and lascivious" behavior has varying definitions across jurisdictions. Indecent exposure, for example, generally refers to the exposure of one's "private parts", which, as noted in a 1992 court case, depending on the jurisdiction, may or may not include one's buttocks, female breasts, or even pubic hair. [6] At that time, 22 states prohibited only indecent exposure of genitalia; "only three States (Indiana, Iowa, and New Mexico), would treat as indecent the intentional exposure of the genital area or pubic hair, and these jurisdictions do so by means of legislation which is explicit in its terms. It thus appears that the term 'indecent exposure' lacks a 'commonly understood meaning', when considered with respect to parts of the body other than the genitalia." [7]
Lechery is a behavioral pattern that includes:
Lechery is not the same as lust. Lust is an interior psychological state, the thinking about sex, the desire for it. Lechery is an outward behavior, a physical manifestation or behavior pattern of an interior condition of lust. Lust does not necessarily result in the action of lechery. [8]
Human sexual activity, human sexual practice or human sexual behaviour is the manner in which humans experience and express their sexuality. People engage in a variety of sexual acts, ranging from activities done alone to acts with another person in varying patterns of frequency, for a wide variety of reasons. Sexual activity usually results in sexual arousal and physiological changes in the aroused person, some of which are pronounced while others are more subtle. Sexual activity may also include conduct and activities which are intended to arouse the sexual interest of another or enhance the sex life of another, such as strategies to find or attract partners, or personal interactions between individuals. Sexual activity may follow sexual arousal.
Lust is an intense desire for something. Lust can take any form such as the lust for sexuality, money, or power. It can take such mundane forms as the lust for food as distinct from the need for food or lust for redolence, when one is lusting for a particular smell that brings back memories. It is similar to but distinguished from passion, in that passion propels individuals to achieve benevolent goals whilst lust does not.
Sex and the law deals with the regulation by law of human sexual activity. Sex laws vary from one place or jurisdiction to another, and have varied over time. Unlawful sexual acts are called sex crimes.
Indecent exposure is the deliberate public exposure by a person of a portion of their body in a manner contrary to local standards of appropriate behavior. Laws and social attitudes regarding indecent exposure vary significantly in different countries. It ranges from outright prohibition of the exposure of any body parts other than the hands or face to prohibition of exposure of certain body parts, such as the genital area, buttocks or breasts.
The United States has inherited sodomy laws which constitutionally outlawed a variety of sexual acts that are deemed to be illegal, illicit, unlawful, unnatural and/or immoral from the colonial-era based laws in the 17th century. While they often targeted sexual acts between persons of the same sex, many sodomy-related statutes employed definitions broad enough to outlaw certain sexual acts between persons of different sexes, in some cases even including acts between married persons.
Sexual penetration is the insertion of a body part or other object into a body orifice, such as the mouth, vagina or anus, as part of human sexual activity or sexual behavior in non-human animals.
Public sex is sexual activity that takes place in a public context. It refers to one or more persons performing a sex act in a public place, or in a private place that can be viewed from a public place.
The labia are the major externally visible structures of the vulva. In humans and other primates, there are two pairs of labia: the labia majora are large and thick folds of skin that cover the vulva's other parts, while the labia minora are the folds of skin between the outer labia that surround and protect the urethral and vaginal openings, as well as the glans clitoris.
Jessica's Law is the informal name given to a 2005 Florida law, as well as laws in several other states, designed to protect potential victims and reduce a sexual offender's ability to re-offend which includes a mandatory minimum sentence of 25 years in prison and lifetime electronic monitoring when the victim is less than 12 years old. A version of Jessica's Law, known as the Jessica Lunsford Act, was introduced at the federal level in 2005 but was never enacted into law by Congress.
Clothing laws vary considerably around the world. In most countries, there are no laws which prescribe what clothing is required to be worn. However, the community standards of clothing are set indirectly by way of prosecution of those who wear something that is not socially approved. Those people who wear insufficient clothing can be prosecuted in many countries under various offences termed indecent exposure, public indecency, nudity or other descriptions. Generally, these offences do not themselves define what is and what is not acceptable clothing to constitute the offence, and leave it to a judge to determine in each case.
Child erotica is non-pornographic material relating to children that is used by any individuals for sexual purposes. It is a broader term than child pornography, incorporating material that may cause sexual arousal such as nonsexual images, books or magazines on children or pedophilia, toys, diaries, or clothes. Law enforcement investigators have found that child erotica is often collected by pedophiles and child sexual abuse offenders. It may be collected as a form of compulsive behavior and as a substitute for illegal underage pornography and is often a form of evidence for criminal behavior.
In the United States, indecent exposure refers to conduct undertaken in a non-private or publicly viewable location, which is deemed indecent in nature, such as nudity, masturbation or sexual intercourse. Such activity is often illegal. The legal definition in a given location may not specify all activities that would be covered.
In the United States, each state and territory sets the age of consent either by statute or the common law applies, and there are several federal statutes related to protecting minors from sexual predators. Depending on the jurisdiction, the legal age of consent is between 16 and 18. In some places, civil and criminal laws within the same state conflict with each other.
An obscenity is any utterance or act that strongly offends the prevalent morality of the time. It is derived from the Latin obscēnus, obscaenus, "boding ill; disgusting; indecent", of uncertain etymology. Generally, the term can be used to indicate strong moral repugnance and outrage in expressions such as "obscene profits" and "the obscenity of war". As a legal term, it usually refers to descriptions and depictions of people engaged in sexual and excretory activity.
Cohabitation in the United States is loosely defined as two or more people, in an intimate relationship, who live together and share a common domestic life but are neither joined by marriage nor a civil union.
The following outline is provided as an overview of and topical guide to human sexuality:
United States obscenity law deals with the regulation or suppression of what is considered obscenity and therefore not protected speech or expression under the First Amendment to the United States Constitution. In the United States, discussion of obscenity typically relates to defining what pornography is obscene. Issues of obscenity arise at federal and state levels. State laws operate only within the jurisdiction of each state, and state laws on obscenity differ. Federal statutes ban obscenity and child pornography produced with real children. Federal law also bans broadcasting of "indecent" material during specified hours.
Naturism in the United States is the practice of social nudity as a lifestyle that seeks an alternative to the majority view of American society that considers nakedness and sexuality to be taboo based upon the legacy of Puritan and Victorian attitudes. Enthusiasm for naturism began in the late 1920s with the establishment of members-only communities where naturists could gather to socialize and enjoy recreation without clothing in an environment that was no more sexual than that experienced while clothed. In later decades some groups began advocating for more general acceptance, and the opening up of public land to clothing-optional recreation.
Inappropriateness refers to standards or ethics that are typically viewed as being negative in a society. It differs from things that are illicit in that inappropriate behavior does not necessarily have any accompanying legal ramifications.
In the United States, individual states have primary jurisdiction in matters of public morality. The topfreedom movement has claimed success in a few instances in persuading some state and federal courts to overturn some state laws on the basis of sex discrimination or equal protection, arguing that a woman should be free to expose her chest in any context in which a man can expose his. Other successful cases have been on the basis of freedom of expression in protest, or simply that exposure of breasts is not indecent.
