Glad someone brought this up. Major major precummer here but yeah when i work my prostate, i basically piss a constant stream of precum. Its the best lube there is. Also try pulling on ur balls as low as u can take it, has similar effect for me. Make a ring around the top of ur balls and pull looooow. Gently but strong. Then use knuckles to rub on your taint at same time. Ecstasy. You will leak massive pre. Peace.
