The ring, designed to be fitted round the base of the penis, consists of a deformable body of revolution (1) having a front face (2) that is thrust against the external peripheral zone of the sexual partner's vagina, and an inner surface (6) that presses against the penis (4). The ring is made from a moulded material, or is hollow and filled with air, liquid or a gel, that transforms the effort (F1) applied to its front face into a pressure (F2) applied to the underside of the penis.
