Abstract: A device to be worn by the human male during sexual intercourse to support the penis and delay ejaculation during the act of copulation, comprising a semi-rigid sheath which encircles the shaft of the penis from the base to a point just behind the glans to shield the same from contact with the vagina of the female, and a support harness to be worn about the lower body of the male and support the sheath to prevent its longitudinal movement along the shaft of the penis during copulation. The harness includes an elongate semi-rigid section having a base portion which is located centrally on the lower abdomen of the male above the penis to firmly engage the pubic bone, and a semi-rigid member which extends from the base portion through the crotch area of the wearer and has a terminal end portion which firmly engages the lower vertebra of the spine to form a dimensionally stable support for the penis-encircling sheath.
