Good idea, hard to use unless you have a very small, thin penis. Please stay tuned if I find a way to enlarge the opening.

If you have much girth this cock ring will not fit comfortably, as it just does not stretch enough. Someone with a penis about 1 1/4 max diameter may find it a better fit.

Adding this ring to a hand job really enhances that experience as well. He slipped it on before I started, and combining the tightness of the ring with the vibrations and my hand, he had an explosive orgasm that threatened to remove the top of his head.
