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.
The early United States inherited sodomy laws which constitutionally outlawed a variety of sexual acts deemed illegal, illicit, unlawful, unnatural or immoral from the colonial-era based laws of the United Kingdom in the 17th century. While these laws 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.
Lesbian, gay, bisexual, transgender, and queer (LGBTQ) people in Gabon face legal challenges not experienced by non-LGBTQ residents. Except for a period between July 2019 and June 2020, same-sex sexual activity has generally been legal in Gabon.
Gross indecency is a crime in some parts of the English-speaking world, originally used to criminalize sexual activity between men that fell short of sodomy, which required penetration. The term was first used in British law in a statute of the British Parliament in 1885 and was carried forward in other statutes throughout the British Empire. The offence was never actually defined in any of the statutes which used it, which left the scope of the offence to be defined by court decisions.
Section 377A was a Singaporean law that criminalised sex between consenting adult males. It was introduced under British colonial rule in 1938 when it was added to the Penal Code by the colonial government. It remained a part of the Singapore body of law after the Penal Code review of 2007 which removed most of the other provisions in Section 377. It was subsequently repealed in its entirety in 2023.
The crime against nature or unnatural act has historically been a legal term in English-speaking states identifying forms of sexual behavior not considered natural or decent and are legally punishable offenses. Sexual practices that have historically been considered to be "crimes against nature" include masturbation, sodomy and bestiality.
The ages of consent for sexual activity vary from age 15 to 18 across Australia, New Zealand and other parts of Oceania. The specific activity and the gender of its participants is also addressed by the law. The minimum age is the age at or above which an individual can engage in unfettered sexual relations with another person of minimum age. Close in age exceptions may exist and are noted where applicable. In Vanuatu the homosexual age of consent is set higher at 18, while the heterosexual age of consent is 15. Same sex sexual activity is illegal at any age for males in Papua New Guinea, Kiribati, Samoa, Niue, Tonga and Tuvalu; it is outlawed for both men and women in the Solomon Islands. In all other places the age of consent is independent of sexual orientation or gender.
The age of consent for sex outside of marriage varies by jurisdiction across Europe. The age of consent – hereby meaning the age from which one is deemed able to consent to having sex with anyone else of consenting age or above – varies between 14 and 18. The majority of countries set their ages in the range of 14 to 16; only four countries, Cyprus (17), Ireland (17), Turkey (18), and the Vatican City (18), set an age of consent higher than 16.
The age of consent in Africa for sexual activity varies by jurisdiction across the continent, codified in laws which may also stipulate the specific activities that are permitted or the gender of participants for different ages. Other variables may exist, such as close-in-age exemptions.
The Penal Code 1871 sets out general principles of the criminal law of Singapore, as well as the elements and penalties of general criminal offences such as assault, criminal intimidation, mischief, grievous hurt, theft, extortion, sex crimes and cheating. The Penal Code does not define and list exhaustively all the criminal offences applicable in Singapore – a large number of these are created by other statutes such as the Arms Offences Act, Kidnapping Act, Misuse of Drugs Act and Vandalism Act.
Lesbian, gay, bisexual and transgender (LGBT) people in Bhutan face legal challenges that are not faced by non-LGBTQ people. Bhutan does not provide any anti-discrimination laws for LGBT people, and same-sex unions are not recognised. However, same-sex sexual activity was decriminalised in Bhutan on 17 February 2021.
Lesbian, gay, bisexual, and transgender (LGBT) people in Dominica face legal challenges not experienced by non-LGBTQ residents. Homosexuality has been legal since 2024, when the High Court struck down the country's colonial-era sodomy law. Dominica provides no recognition to same-sex unions, whether in the form of marriage or civil unions, and no law prohibits discrimination on the basis of sexual orientation or gender identity.
National Coalition for Gay and Lesbian Equality and Another v Minister of Justice and Others is a decision of the Constitutional Court of South Africa which struck down the laws prohibiting consensual sexual activities between men. Basing its decision on the Bill of Rights in the Constitution – and in particular its explicit prohibition of discrimination based on sexual orientation – the court unanimously ruled that the crime of sodomy, as well as various other related provisions of the criminal law, were unconstitutional and therefore invalid.
This is a list of important events relating to the LGBT community from 1801 to 1900. The earliest published studies of lesbian activity were written in the early 19th century.
A sodomy law is a law that defines certain sexual acts as crimes. The precise sexual acts meant by the term sodomy are rarely spelled out in the law, but are typically understood and defined by many courts and jurisdictions to include any or all forms of sexual acts that are illegal, illicit, unlawful, unnatural and immoral. Sodomy typically includes anal sex, oral sex, manual sex, and bestiality. In practice, sodomy laws have rarely been enforced to target against sexual activities between individuals of the opposite sex, and have mostly been used to target against sexual activities between individuals of the same sex.
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.
Lesbian, gay, bisexual, transgender, and queer (LGBTQ) people in Seychelles face legal challenges not experienced by non-LGBTQ residents. Same-sex sexual activity has been legal since 2016, and employment discrimination on the basis of sexual orientation is banned in Seychelles, making it one of the few African countries to have such protections for LGBTQ people. However, LGBTQ people may nonetheless face stigmatization among the broader population.
Lesbian, gay, bisexual, transgender, and queer (LGBTQ) people in the U.S. state of Kentucky still face some legal challenges not experienced by other people. Same-sex sexual activity in Kentucky has been legally permitted since 1992, although the state legislature has not repealed its sodomy statute for same-sex couples. Same-sex marriage is legal in Kentucky under the U.S. Supreme Court ruling in Obergefell v. Hodges. The decision, which struck down Kentucky's statutory and constitutional bans on same-sex marriages and all other same-sex marriage bans elsewhere in the country, was handed down on June 26, 2015.
Capital punishment as a criminal punishment for homosexuality has been implemented by a number of countries in their history. It is a legal punishment in several countries and regions, all of which have Islamic-based criminal laws, except for Uganda.
Rape laws vary across the United States jurisdictions. However, rape is federally defined for statistical purposes as:
Penetration, no matter how slight, of the vagina or anus with any body part or object, or oral penetration by a sex organ of another person, without the consent of the victim.
