Pederasty
Pederasty (or paederasty in Commonwealth English) (/ˈpɛdəræsti/) refers to same-sex sexual relationships between an adult man and an adolescent boy; some authors also use the term to refer to same-sex female relationships with a similar age gap. Pederasty existed as a socially acknowledged and accepted practice in some premodern societies.
In most countries today, the local age of consent determines whether a person is considered legally competent to consent to sexual acts, and whether such contact is child sexual abuse or statutory rape. An adult engaging in sexual activity with a minor is considered abusive by authorities for a variety of reasons, including the age of the minor and the psychological and physical harm they may endure.
