i sometimes feel a little bit itchy near the testicals, and i dont feel burn or something like that at all. I have unsafe 1 time with a stranger in December/January, sorry i cannot remember, but that sex happened really quick because after giving me oral sex for 5 mins, we started to do anal without condom but i was too scared so i stopped after 5 mins and got home immediately. Can someone help me?

hey Eric

from the first 3 pics your penis looks healthy and nothing is a problem. Only from the last one there is a small white mark on the left of your Shaft but it doesnt look concerning to be honest.
