Penis or Erection enhancers are male sex toys that boost the length, girth and staying time of an erection. These adult toys include cock rings, penis sleeves and penis extenders. Cock rings are male toys that slide down to the base of the penis or behind the balls to help maintain an erection. Many cock rings also come equipped with a bullet vibrator for clit stimulation. A penis sleeve is the best choice to add girth to the penis; sleeves usually have deep grooves or nubs for added pleasure, and sometimes they have a small vibrator as well. Penis extenders are realistic sleeves with penis head that can extend the natural shaft from 1 to 4 inches. Each type of erection enhancer has it's own special uses for making your cock even better.
