8” length is perfect and you don’t need any bloody surgery for your girth. Get a pump and use it. It’s easy and fast. Start pumping mornings, afternoons and nights at low pressure with warm water for 20 min in a large tube (3.5” diameter): it works fast and well. In time a good portion of your temporary gains will become permanent and you’ll also gain some extra length. You may even clamp better afterwards, just don’t overdo it, injuries could take you out of the game (of fucking, forever..!).
If this were a world of 8” penises, surgeons would be in deep trouble.
