I use to use toothpaste to try and get rid of the milia on my penis, also i scrubbed the area vigorously with soap in the shower.the skin is now discolored, scarred, and tight,and my penis doesnt stretch like it used to, my penis contracts often?

Options: Your decision to use this combination of chemicals on sensitive skin created a chemical burn & scarring. You will need to consult with a urologist to see if they can offer an option that may help reduce the scarring & return function to a more normal pattern. Any therapy would require an in person exam to properly assess the damage.
