In stretching it seems that the meatus is the limitation and that is were the pain comes from. I have tried the 8MM rod and after it has been in for 5-10 minutes the pain will go away until I remove it. I have left it in with the gland ring on for 18 hours until finally is was more uncomfortable than painful. How long do I leave something like this in to get the stretching done? I would like to get to the point that I can just drop in the 8MM sounding without having to push past the meatus. What is a typical routine for stretching?
