I have been fighting on and off with a rash around my testicles and inner theigh. I have been putting prescription creams on the area. The area has not hurt in many weeks but still gets deep red and pinkish when the rash appears to be going away. I am in a relationship with girl. There seems to be a pattern. THe rash will seemingly begin to disappear but after we have intercourse the rash will begin to get more red the next morning. My girlfriend has shown no signs of having a yeast infection but has used monistat to treat it just in case. A couple of days after treating it I still got red again. What is happening? Am I having some sort of reaction to her vaginal secreations? I'm at a loss here, and very frustrated. I have spent so much money on doctor's appointments and creams that don't make the problem go away.
