Bottom surgery refers to gender-affirming surgery aimed at altering an individual's genitalia to better reflect their gender identity.

Bowers v. Hardwick (1986) was a landmark decision by the United States Supreme Court that upheld the constitutionality of a Georgia sodomy law criminalizing oral and anal sex in private between consenting adults when applied to homosexuals. This decision was significant for its time, as it affirmed the legality of state laws that specifically targeted homosexual acts, thereby legitimizing discrimination against the LGBTQIA+ community under the guise of upholding public morality. The ruling was a major setback for LGBTQIA+ rights and was widely criticized for infringing on the privacy and equality of gay and lesbian individuals. It represented a legal endorsement of the criminalization of homosexuality, contributing to the stigma and marginalization of LGBTQIA+ individuals. Bowers v. Hardwick was eventually overturned by the Supreme Court in the 2003 case Lawrence v. Texas, which ruled that such laws were unconstitutional.
