English Wikpedia

Intercrural sex (from inter- and Latin crura, "legs"), also known as femoral/interfemoral sex/intercourse, is a type of non-penetrative sex, in which a male places the penis between the receiving partner's thighs (often with lubrication) and thrusts to create friction. Intercrural intercourse was a common outlet for pederasty in ancient Greece, because anal sex was considered demeaning to the receiving partner. The Ancient Greek term for this practice was διαμηρίζειν diamērizein ("to do [something] between the thighs").
