ok ill try to explain it as best as possible. i have this rash that covers an area around my penis. not the penis its self but the area out side. it has a border were it stops and it just stops flat out no slow down or decreasing. it itches really bad and ive had it for a while now...maybe about a year. i no it sounds crazy i havent checked it out before but i thought it was just irrated or something. ive looked on line for some explanation but nothing seems to fit.
