My girl woke up with cold sore on her lip today..?

Okay My ex-Boyfriend had cold sores,and I let him "go down" and now my whole "private" area is full of these bumps with puss in them.It burns so bad.The smell is horrendous... Where did she get the cold sore from? Don't kiss her because then you will get cold sores for the rest of your life,also DON'T LET HER SUCK YOUR P*&^% because you will get what I have..Hope hers goes away soon so you can get back to the "dirty" :D
