If you find a good acupuncturist they will place needles in arms, legs and lower abdomen for at least 30 mins. Should go for 8-10 visits but you should have improvement after a couple. There’s one point that is rarely used bec it’s intimate and not all docs will go there. It’s Ren1. If you look it up you’ll see what I mean. Sometimes heat or electric stim is applied to the needles. You have to be healthy, fit, not over drinking or on some drug that inhibits erections for any treatment to be effective. Always start with physical and mental health. Both are linked to performance.
