I have this red line on my vagina lips (on the outside tucked in its cleavage) it stings when it's touched and I am worried that it may be herpes. I've only had sex with one guy and we used a condom, but there was one moment when his head touched the opening of my vagina without a condom on, and I pushed him out. I'm not sure what is going on...does this sound like herpes, or can it just be an irritation from thongs, swimsuits, wearing jeans without underwear??? He told me that he didn't have any STI's, but I have no idea if he was telling the truth or not. I plan on getting tested, but it would be nice to have some advice for the time being. Please help. thanks!
