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 retracts easily now.

Stop self-injuring !: Tooth paste wasn't designed for use on the penis. Scrubbing vigorously can cause damage. At this point, I can only encourage you to stop the self-injury. Depending on severity, you may wish to see an urologist.

Toothpaste: T'paste is formulated for use inside the mouth, not on. skin. You may have created permanent scarring. Please see a Urologist or a Dermatologist immediately. Perhaps they will have a solution for you.
