how to maintain 50% erection
I usually get full erection easily. I try to maintain 50-60% erection since this is the suitable erection for gaining length and avoiding hard veins. I do that by hot wrap interruption each time I feel I’m about to get full erection. I read if you don’t have spots on the head then you are not peing enough. This indicator drove me crazy so I begun peing near or full erected. The results after the session were noticable. But don’t overdo it.
One of the things I aimed at from pe is to retard ejaculation. I think this can be achieved but need more advice and more experiences.
