My girlfriend an I have what appears to be a fungal infection in the pubic region. I believed for awhile that it was tinea cruris, or jock itch, which seems to be a common one. However, I have recently learned that jock itch does not tend to affect the scrotum and penis as much as the legs and crevices between the legs and scrotum. This is almost exclusively on the scrotum and penis, and the scrotum is starting to shrink and tighten and turn gray. There is almost gray discoloring on my girlfriend.
