End half of penis darker than base half
All I have been doing is jelqing at about 80%, very very slow reps. Just for the purpose of visualization, it looks as if the end half is tan and the base half hasn’t gotten enough sun… there is a clear tan line down the middle to separate the colors.
1. I noticed it was happening during my jelqing session, was I jelqing too intensely?
2. What does this mean? IE. What caused this?
3. Is this just a form of discoloration and is it common?
