These posts seem to indicate that you really do not know whats going on in the area of PE to stimulate growth. Some exercises require a relative small amount of time to improve growth potential, you can tell by the effect and appearance it has on your penis. In this perspective, it is similar to muscle building, in that you can feel a “pump” or satisfactory fatigue that elicits growth. Morning wood, turtling have little or almost nothing to do with generating growth. In my thinking, anybody doing 100-200 jelqs is an idiot, does anyone do 100-200 repetitions in their resistance exercises?
