Hi,
I am opening this topic as i could not find a lot of informations on internet regarding my issue.
I have a brown mark on the inside part of my foreskin, means i can only see it when i pull my foreskin. it is there for few months now i believe, i did not really pay big attention when i first saw it, however, i have been reading a lot about potential cause lately and it got me very anxious/stressed.
Please also note that i dont feel any pain, if i touch it it seems to be similar thickness and texture than the surronding, and i have recently been tested with full std screen which was all negative. Not really been sexually active since then, and always protected anyway.
Can someone please help me to find what it is ?
I will try to post few pictures to show you my symptome.




Thanks a lot
anyone would have an idea or similar problem ?
Are you are sports person, do regular physical activity, ride a road bike, gym workouts that kind of thing?
You may have the regular presence of moisture in your groin region and eventually this gets under the top layers of skin.
not really into sports for a while now. and even after shower i always dry my whole body well, including this area
I suggest you see a Dermatologist …
I also have the same, issue plus 2 moles. Never got bothered by black area, I guess it might be because of some kind of trauma
