Hey man, how has the Japanese silicon ring worked out for you? I just ordered one after reading your thread. I have had balanitis of the penis for 3 years now and have a circumcision date pending. I do NOT want to get circumcised and I am sick of putting anti-fungal creams on my penis. The device you posted is EXACTLY what I have been looking to find for about 2 years now.
I hope you have good news!
