Hello,
My girlfriend has a rash, below her belly button. The patch of skin is tough, almost scar material in nature. It is usually tolerable but seems to aggravate when foreplay is initiated and she scratches it, incessantly, subsequent to intercourse? She's had it, since before we started dating, almost two years now; we thought it might be a nickel allergy but no treatment seems to make a decisive improvement. It is obviously of serious discomfort, to her, any thoughts?
