I have had a red rash on the top of my groin area above my penis....thats goes away after a few days of no sex and then comes back when I have sex...its itches and then peels away...this was for months....and just recently it turned to blister that itch on the same area and some on my penis....they are not pussing just some have a black spot and others area just decently sized red bumps...seems to be drying up and its been two days...lymph nodes are sort of enlarged in my groin area....could it be a yeast infection that i never treated...anyone have a guesS????
