Hi,
I notice a bulge on the right side of my penis shaft when masturbating, there is no change in colour or texture when i touch it, and it is on the right side of the upper third of the penis. Nothing could be noticed under the skin, just a bulge that makes the skin on the right side thicker than the one on the left. Also, there is another lump on the "dorsal" side of the penis, and a little bit to the right ( which makes it close to the first one), but this one is small (sesame size), concentrated, has a bit of a colour, and i can feel it under the skin when i touch it. Both of them cause no pain, and both of them I only see/feel when erect.
what could this be? and what should I do?
