I have been with the same guy for 4 years, never cheating on eah other. Never had a disease before. After sex the otherday, I found 1 hard bump on the outerlip of my vagina. It is a little tender and not very big, size of a pen back, and red. Do herpes always look like the ones in the pictures on this site? My bump does not. Could it be herpess?? There is only one and Iv never had anything like that before.
