Abstract: An elastic band with a tapered bore extending therethrough is positioned on the base of the penis for maintaining a penile erection. Flanges extend radially from the base of the band to stretch it and spread it sufficiently for application. When the stretching force is released the residual elastic force in the band constricts the base of the penis to restrict outflow of blood from the base of the penis. The elongated structure also provides physical support at the base of the penis as an aid in supporting a penis afflicted by Peyronie's disease or the like at the penis base.
