Pumping safer then Jelqing?
I was thinking about the reported erectile dysfunction some people experience that do PE. The main culprit must be Jelqing since merely stretching doesn’t seem like it would be effecting the valves.
Jelqing increases blood pressure in these valves and weak valves could be damaged by this pressure, essentially the valves are being made to resist a pressure above what they were designed to which causes failure in those with already weak valves.
I was thinking hydro pumping (bathmate) or regular pumping might be a safer option because the blood is being pulled not pushed into the penis ie negative pressure not positive pressure. Also since its not necessary to have an erection whatever mechanism which retains blood in the penis whilst having an erection does not come into play.
I wonder if there is a correlation between those who get ED from doing PE and those with varicoceles?
