Does pumping cause hypertrophy? And could dietary bulking help PE?

Im asking as having an idea of how pumping works on a physical level on the various penile tissue I think it should cause hypertrophy but when I look it up, Google tells me it doesn't, and that pumping is not permanent for that matter so if anyone could just tell me here as sounds like "there is no way to increase size in any way shape or form" BS. Also, could implementing a bulking diet regimen help with PE gains? I know it'd be inefficient as shit and that alot of it would go elsewhere but would it help with PE at all?
