Herpes?? Help!

Bethany
My boyfriend and I have only ever been with each other. We haven't had sex in 8 months but we did oral this weekend. I have what looks like a pimple or an ingrown hair on the upper, front part of my v. My boyfriend is worried and found a red spot on his penis. He is convinced he has herpes but there is no way because we've only been with each other right?
