Hello, my husband and I have been apart for almost 5 months. He is about to return home and told me that he has a rash on his penis. He believes it is from poison ivy. He said it formed sores and they have opened up. The rash has lasted about 2-3weeks. He has not had it looked at. I am concerned one about his health and clearing this up and two being sure this is not an std. How should we proceed?
