I have developed a rash on the shaft of my penis and quite bad on my area between scrotum and anus(Not in my anus) The rash on my shaft is red and runs all up my shaft its a little raised but not blistery or ulcerated. the rash between my scrotum and anus is red, raised and covers quite an area, goes in a line from just above my anus to my scrotum and then spreads to my inner thighs. itchy at times but not over powering. Sore to walk(Like chafe but had chafe before and this is different) I had unprotected oral but protected vaginal 2 times in the last 8 weeks and never had this before.
Any help would be appreciated.
