Open sores on my vagina and I recently had a cold but I don't how it can be herpes because I've only had sex with a virgin and it was months ago?

Somebody's lying. Open sores are never normal - even after a cold (wrong neighborhood). Herpes hurts! On the other hand, 25% of people have herpes but 90% don't know it. If your virgin friend performed oral sex on you, you have a 2/3 chance that it's herpes I (not so bad) and a 1/3 chance that it's herpes ii (worse!). Herpes may lay latent and come out months later during times of stress (injury, deadlines, family).
