Ive got 2 questions here, or two problems more like... Ive had 2 dark spots on my penis since about 7th grade, one on the head and the other just below it. They're painless and look somewhat like birthmarks, Im currently 18 years old and they have never given me trouble and Im curious as to what they are. Secondly I recently had unprotected sex with a girl who I didnt know all that well, and during the first night she was a bit dry and I kinda rubbed myself raw. The next morning I had a sore penis, but the next day the skin on the head got hard and started to flake off... is this an STD or just a result of dry sex?
Dark spots, and skin irritation
The dark spots are probably just pigment changes. I doubt there is anything to worry about. Did you have some sort of sore there at one time? Scarring will cause skin to turn dark sometimes.As for the dry skin. You may have something like a yeast infection. Although straight irritation could cause it too. Try using some lotion to keep it moist, maybe something like neosporin to help it heal, and if it isn't better in a couple days you should go get it checked.AND NEXT TIME...Use a condom. Save the worry.
