Intercrural sex

Inter-crural intercourse is a type of frottage practiced mainly by gay men. It involves placing the penis of one partner between the thighs of the other partner, rather than against his penis, and rubbing to create sexual pleasure. It is also known as the "Princeton fuck".

In Ancient Greece, this was practiced in a very ritualized fashion by young men and their "mentors" of sorts. The mentor, generally an older man, would choose the young man to teach about the ways of the world. The pair would engage in intercrural intercourse, the old man "penetrating" the younger. This was not a homosexual practice as such, but more of a ritualistic one. Society at that time accepted this practice, however, it was considered extremely taboo for the roles to be reversed.

Inter-crural intercourse carries some pregnancy risk when practiced by heterosexual couples.
