If not through traditional means of physical activity or exercise, then how? Depending on the pump you can have your penis flaccid, hard or semi-erect.
While minor edema does not damage the penis, over-pumping can cause painful blisters, ruptured blood vessels, and in some cases, permanent ED erectile dysfunction.
I had heard a lot about penis pumps, a few of my sex blogger friends had told me to buy one and I had done extensive research on what they can actually do for me before I eventually just decided to go ahead and buy the most popular one.
