Hi, about 3 weeks ago I noticed a darker spot of skin right where my thumb goes when I masterbate so I switched hands to avoid the spot. Well all that did was cause an even bigger spot on the other side. I then became super worried and stopped masterbating all together 14 days ago. The problem is that I have seen no improvement. Personally it takes a long time for my body to heal from bruises and etc but this is just ridiculous. To go into more detail the spots are right where my thumb constantly rubs during masterbation and it is just a darker shade of skin then the rest but doesn’t itch or hurt it’s just a visual thing so far. I haven’t gone to a doctor and I was wondering if this is nothing to worry about or if I should pay mine a visit.
