Thanks for the reply... I have bought both metal rings and leather stretchers. The metal ones always manage to slip off during the night so I went with leather. The balls dont turn blue or get uncomfortable so Im going with those. Right now i've got a 1.5 " stretcher on but I bought sizes up to 4" so we'll see.
I do try to take a hot bath once a day and stretch them out for about 5-10 minutes. After this they are loose, but at some point in time they do return to tightness.
I also shave them about once a week or so, so that's in order. I guess I will just go with the flow for now. Thanks again
