"Pocket pussies" or "vaginas" or "masturbators" are modeled to accept a penis for simulated intercourse. They can be shaped like vaginas, anuses, or anything with a hole for penetration.

Cock rings prolong male erection by withholding blood inside the penis. A man may wear a cock-ring to combat erectile difficulties, or because for the sensation of tightness and engorgement that wearing one provides. Some models include a protruding clitoral stimulator, designed to stimulate the clitoris during sex. Others vibrate, either vibrating the ring itself, or in a popular 'Dolphin' variant by using two removable bullet vibrators to provide stimulation to both the testicles and clitoris. Some cock rings also have vibrators attached which can be worn to stimulate a partner during sexual intercourse, especially in the scrotum or perineum.

A triple crown is a special cock-ring that has additional rings for restraining the testicles. In orgasm, the testicles usually retract toward the body before ejaculation. A triple crown changes and intensifies the sensation of orgasm by forcing the testicles to stay away from the body.

A cock harness is a more elaborate harness designed to be worn around the penis and scrotum. Its function is similar to that of a cock ring. These devices are often associated with BDSM activities such as cock and ball torture.

A ball lock is an ordinary padlock fastened around the male scrotum, separating the testicles away from the penis and not removable except by key or combination.

A penis sleeve is a cylindrical device that is placed on the shaft of the penis, with the aim of increasing stimulation for the person being penetrated. They often have soft bumps intended to provide further stimulation.

A penis extension is a partially hollow device like a very short dildo, with the hollow end placed on the end of the penis, intended to increase the effective length of the penis, again for the benefit of the person being penetrated. These are generally worn with condoms to prevent them from falling off during use.

A docking sleeve is a cylindrical device similar to a penis sleeve, but is open at both ends, so that two men can dock.
