Blue black marks on Glans
I noticed blue-black marks on my glans, near the frenulum region and at an old injury spot (accidentally injured by the ruler when measuring).
There’s a slight pain feeling on the glans.
I have been doing stretching, wet jelq, pumping and wrapping (tighten wrist bandage around shaft).
I am not sure whether the blue-black marks got to do with any of these.
Does anyone else also experience blue-black marks on his glans?
