What can i do to increase the size of my penis and last at least 5 minutes with my wife?

It's not the size of the tool, it's how you use it. If there was a way to increase the size of your tool with a potion, lotion or pill the creator would be a multi quadrillionaire.

Increased penis size does not result in better sex- unlike common perception, The duration can be prolonged by mutual understanding in a natural way without getting the clock involved. Its the quality and not the duration which is mutually satisfying- which both of you can work out together Good luck
