So afew weeks ago, my penis seemed to have small circular bump close to the head but on the foreskin and after afew days it turned black and it doesnt itch or changed any other color but one day I was curious so I picked at it and removed the skin, not very painful but it looked like dead skin? Not sure but I thought after doing that it would go away or heal? But it didn t and it did not get worse, it just turned circular and black again like before and so I don t know if its herpes or STD s but I m worried because I ve never had this before and I m young and I have not had sexual intercourse in awhile and I m worried, can someone help me with how to treat this? And is it an STD? Please help
