I am in my early 50 s, and when I have an erection there is an circular indentation a few inches up on my penis. The area between the indent and the head is narrower than at the base. I have no issue with erections or function, but it wasn t like this before and has been like this for a few months.
Than for asking in Chat Doctor forum I appreciate your concern. If you have normal functioning penis you need not worry much. It may be due to injury and scar tissue which is causing indentation. Visit a surgeon for opinion regarding this. All the best.
