Walgart, try Maca, L-Arginine, Ginseng and/or Ginkgo. Also, hot wrap your unit several times daily. Also, I always recommend avoiding ejaculation, and to have frequent stimulation. That means you can masturbate, and get nice and rock hard, and then kind of stimulate yourself without pushing yourself over the edge. And never go past the point of no return. Just stop after awhile. You’ll find that your penis gains a lot of strength and health from this exercise, and it can aid in recoveries. Contrarily, the more you often ejaculate, the more often you cause detriment to your penis health and make it more difficult to recover from injury.
