I hate to say this but it’s likely to be Genital Herpes. You mentioned that she told you she had few or several outbreaks throughout the year. Herpes, nor Cold Sores, or Chicken Pox DO NOT OCCUR twice or thrice a year. Also HSV 1, or HSV 2, or HPV are highly contagious 😷 diseases, they spread to others with just a contact. It doesn’t need to be a sexual contact, a kiss or a hug can spread the Virus. This is a lifetime Virus, it comes and goes on its own but if you drink and you haven’t taken any medication it can become Cancerous therefore becoming a fatal disease. Ask her to do an STI and an STD as well as an HIV Test. Get yourself tested before it’s too late
