What is genital HSV-1, and how can it be treated?

Hello doctor,

I am a 28-year-old male with no notable medical conditions or abnormalities. I used to get cold sores on my mouth when I was young, but have not had it in many years (I assume HSV-1 since oral HSV-2 is rare and since, at that point, I was not sexually active). Strangely, last week I had an outbreak of genital HSV-1 (per the test results) and, before being tested and not realizing what it was, unfortunately, passed it on to my partner, who had never had cold sores and the virus before. Her genital outbreak also tested positive for HSV-1. I know it is rare, but rare implies that it does happen sometimes, and I must be one of those cases. Normally it is unlikely to pass genital HSV-1 to someone who has oral HSV-1, but since that did happen to me, am I more likely to similarly infect the genitals of someone who also has had oral HSV-1 in the past? Currently, I am on Venlafaxine (depression), Buspirone (anxiety), Lisdexamfetamine or Vyvanse (ADHD), Valacyclovir (temporary, for HSV-1 outbreak), Clyndomycin (for staphylococcus infection that occurred during flu-like sickness from the outbreak). Also, does this change the likelihood that I will infect someone who has never had the virus? Can I expect outbreaks in both places, or has it "moved"? Do I need to take any precautions (medication or otherwise) for myself or for any partner I may be in contact with in the future? What is recommended for genital HSV-1? You can provide any additional info that I did not specifically ask for. Thank you.
