The last time I had sex was in August. Before then I had small bumps that would come and go on my vagina. I have be tested for STDS and they have always come back negative. I have not been tested since August. I have small single bumps that come and go on my vagina. They never stay for long. They don't itch, but sometimes they can be painful. I am starting to experience a little iritation in my vaginal area. There is no discharge, just feels like a slight irritation. Do you think this could be an STD and if so could it be warts or herpes?
