I have a question concerning veins on the penis. For a long time now, I have had a vein on my penis which is quite visible. The other day I noticed another vein on my penis that was becoming more noticeable. I know that there are no physical problems with having visible veins on my penis, but I don't like it. What has caused these veins to become more visible and how do I cover them up? I j/o frequently, and am 19 years old. I know this is a cosmetic problem, but it's an important problem to me. Thanks for your time.
