Bodybuilders lift weights to the point where they cant lift their arms. But they also take daily Mass Blood Flow supplements (NOS,Largine,etc) that helps them recover quickly from a exhausting workout. Now once its all done; they now find themselves with the extra mass and strength to knock out that H.S bully. So PE is the same. Stretch to your dick feels like it cant no longer move. Take NOS daily in order for your penis to recover. Keep this consistent and 6 months from now. You will find your penis with the extra mass gains and strength that will make your lady realize that you are truly knocking that vagina out. Now once you get to that point; make sure you give her a couple of strokes for Disco Dave and any other PE brothers around the world who may not be phucking that night. Good luck on your journey.
