I have a rash on one of my outer lips of my vagina. I am married and have been for 3 years so I am not so worried about an STD, but it itches like crazy. Should I just go for some kind of cream. What could it be? I also know that I have been test for HPV, could the itchiness be genital warts? It is only on one side and nothing itches on the inside. Thanks.
