Hey, that's nothing. I once rode fifteen miles on a Honda Goldwing with my dick in a 2" tube at 10 inhg, because I had a hot babe waiting for me. Clamping while driving a car is a piece of cake. I also once removed a clamp, jelqed in fresh blood and reclamped underneath the table in a restaurant. Dedication is the name of the game. Some guys say they have no time for PE. I say make time.
