  • Patent number: 6991600
    Abstract: A male sexual aid is made of soft and elastomeric material such as rubber, silicone rubber, or latex. The device is composed of a hollow tube and two rings arranged on two lateral sides thereof. The hollow tube (tubular cone body) has only one opening for accommodating a micro-vibrator or LED capsule. The two rings include a testis ring and a penis ring. In usage, the two rings respectively embrace the base of the testis and penis in parallel or crosswise so that the erected penis extends and lasts longer. Moreover, the hollow tube holds tightly on the top of the base of the penis so that the device stimulates or vibrates the clitoris of females for increasing sexual pleasure during intercourse.
