I have been masturbating for 5 year and for the last one and a half years I have only had the feeling of the orgasm in the left side of my penis the right is totally numb, I have read that if you push your penis down while erected it can damage it witch I have done before. I also read that it could be a clot , and on the right side of my penis there is a bump sticking out like a vein and I thought that might be the problem. Please help!!
