Genital herpes?

Me and my ex (both virgins, still virgins thankfully) had oral sex while he had a cold sore on his lip. Multiple times. We were both unaware that this could cause genital herpes. I have recently noticed that I have been suffering from headaches, cold sweats, horrible pain and itching, tingling, and worst of all, little red blisters that rupture and bleed, causing beesting like pain. I looked down there with a mirror and counted at least 20 of these little monsters, and they are spreading to my butt. However, these symptoms are also consistent with a yeast infection. What are your thoughts on this? (PS, I've only ever been sexually involved with one guy, we were each other's firsts on everything)
