Abstract: A phallus retention garment, such as a lower body underwear garment, with localized stabilization of a retained prosthetic phallus in relation to an underwear structure. A crotch portion with a phallus retention aperture can form a phallus retaining portion. The underwear structure has a body portion, a waistband secured to the body portion, and first and second leg openings formed in the body portion, all of which could be resiliently stretchable as could be the phallus retention aperture. One or more panels of substantially non-stretch or inelastic material can partially or completely surround the phallus retention aperture to provide localized stabilization. The garment structure can be formed with one or more layers of elastic material, and at least one layer of substantially inelastic material forming the stabilization portion can be fixed to the layer of elastic material adjacent to the phallus retention aperture, such as by stitching in a pattern.

Abstract: A phallus retention apparatus for retaining a prosthetic phallus relative to a hand of a wearer with a sheath, a thumb aperture in the sheath, and a prosthetic phallus aperture either directly in the sheath or in a retention flap coupled to the sheath for receiving a shaft portion of a prosthetic phallus. The phallus aperture is spaced from the thumb aperture to position the phallus aperture approximately centered on the palmar side of the sheath. A phallus retention apparatus can retain a prosthetic phallus relative to an external structure with a base panel, a retention panel, and a phallus aperture in the retention panel for receiving the body portion of the phallus therethrough.
