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 "Oxford style" as opposed to "the Princeton rub" (traditional frottage).

Inter-crural intercourse was the method of sexual expression in Greek pederasty. It carries some pregnancy risk when practiced by heterosexual couples.
