A condom retainer ring structure (20) is for use on a condom (10) that has an elongated thin walled tubular sheath of resilient material closed at one end and opened at the other end, with a bead surrounding the opening. The condom retainer ring structure has a first ring (22) for positioning at the periphery of the opening, adjacent the bead that surrounds the sheath. A second ring (24) is connected to and adjacent the first ring. A bridge (26) having a retention notch (28) therein joins the rings generally in a single unflexed condition. In use, when a condom (10) is worn on the penis of a user, the first ring (22) surrounds the sheath on the shaft of the penis, the second ring (24) encircles the scrotum to anchor the condom, and the bridge (26) is flexed thereby, constricting the retention notch (28). The retention notch (28), preferably positioned over the bead of the condom, grabs the bead to retain the condom.
