Yeah, honestly it sounds like she might have. Doesn't she go to the gyno? She would have found this out before now if it had been present this whole time.
She's had aches and pains before but not until recently where she had a "pimple". She got worried and decided to go check it out. Gyno doesn't test for stds all the time, she gets papsmear every now and then but she never would of thought to get tested for this. Even though her former cheated on her a lot.
As for me, I never got an outbreak and the "outbreak" that I did get could of seriously been from having sticky hands.
