Isn’t it the area running through the prostate area or in general closer to the bladder that determines the flow rate more than the opening? I have had this for years; since I was a teenager. So I know it’s not the BPH symptoms that correlate with old age (and I’ve had my prostate checked to be sure). I can just feel that the opening isn’t really holding it back, rather it’s just emptying slower further upstream.

I’d be interested in hearing from someone that has used a sounding or other regimen to try to improve this and made real progress. It impacts my quality of life, because of the reasons the others cited, and also because it makes it hard to start sometimes.
