Hi, these two black (light black) spots appeared on the shaft of my penis a week ago, they don't hurt are smooth to the touch and when the penis is erect they dissappear. Im not sexually active and I think they are just bruises from hard mastrubation but I would like to hear a different opinion about them. And they are not bumpy. From my search on the internet I couldn't find anything, so please help me out. The file size for the pictures are too big so I compressed them, if the quality of the picture is bad I will upload it to a 3rd party and post the link here
Here are more pictures with circles so you can see better
Your suggested link with masturbation could well be what is going on.
However, I cannot see any of the detail in the photos you have posted - try to get a clear close-up of one of the black areas and post it on her as I will not view 3rd party sites.
Try to ease back on your masturbation for a week or so and see if these disappear
Also, I wonder if you apply anything to your penis, before, during or after masturbation?
Seems like I cant post a HQ picture on here. Nevertheless I will try to ease of mastrubation for a week. Thank you for the reply
