Diamo works for me
My Diamo just arrived yesterday and my overall impressions are very good - with a couple of caveats. First off, I'm very fortunate the my correct cock ring size is 1 and 3/4", the size of the Diamo ring. Read about the correct way to measure yourself. If I needed bigger I could never get my stuff in there. If I needed smaller it would fall off when I move around. The second thing is that vibration around the base of my cock and over my perineum, which the Diamo does excellently, doesn't give me an erection by itself. What it does do, however, is put me in a hell of a horny mood. If that wasn't enough, after about a hour of Diamo stimulation and then removed, my body stays in a heightened, tingly state, for hours. I feel like some kind of primal sex creature.
