Abstract: A prophylactic device adapted to be worn on a penis. The device includes a bottle-shaped, tubular sheath open at both ends and an elastic band attached along one of the ends of the sheath for securing the sheath to the glans of the penis. The tubular sheath is operable to prevent constant contact between clothing and the glans of the penis while, at the same time, permitting normal micturition functions. The band is relatively thick and wide to form a roll-preventing perimeter and further includes raised, generally longitudinally extending ribs arranged about the outer surface of the band for preventing the band from rolling up. In an alternative embodiment, the sheath includes an inner layer and an outer layer defining a region therebetween for receiving a tactile preventing substance. This region may include a series of parallel baffles along its inner surface for slowing the flow of the tactile preventing liquid.
