Abstract: An erection holder to enable or prolong an erection of the penis of a man. It has a body of sleeve-like configuration with an outer sleeve wall surface, a hollow interior surrounded by an inner sleeve wall surface, a base end destined for coming to rest, during use, against a portion of the user's abdomen, surrounding the root of his penis, and an outer end. Openings are in the base end and the inner end. A first inwardly directed protrusion surrounds the opening in the base end and a second inwardly directed protrusion surrounds the opening in the outer end. A circumferential lip portion extends from the base end in an axial direction and is preferably integral with the body of the holder and preferably forms a circumferential blunt edge with the said first protrusion. Between the two protrusions the sidewall of the body is outwardly curved and preferably barrel-shaped.
