Any thoughts on what is the typical cause of Erect penis shortening?? I am almost an inch smaller in erect length than I used to be.... Since adopting certain supps like Pansterone, kuinone, etc my flaccid length has actually increased, however my erect length over the past few years has significantly gone down in size. Any thoughts? Can low estrogen do this? Ill continue with pansterone and applying it to the gonads in hopes to improve this, but I'm at a loss...
