I have tried most combinations. There really is nothing for it but trial and error.
I have severe venous leakage though, to the point that an implant may be in my future. (That\'s another story....lol).
They are medical bands, so they are totally different from a normal ring. These are super tight. They almost cut off blood outflow entirely.
You have no need of this unless you are having real erectile dysfunction issues. Which you may be.... now that I see you\'re looking at pumps.....unless you\'re just pissed. ?
The loops are just to lift it off enough to get your fingers under the band itself, then you pull it off. Use the loops to pull them off and they will just break. I learned this the sore way lol.
