First, I am so sorry to have missed your post.
It doesn’t work biologically that you will pass this back and forth. Each of your own immune systems will handle this virus in its own way. HSV does not make you more susceptible to yeast infection, except perhaps with a primary infection. You are not at any real risk of developing an outbreak elsewhere unless you were infected elsewhere without showing any symptoms and then, one day, show up there with lesions.
With genital HSV 1, you may never have another outbreak – many people don’t
Please feel free to keep asking questions.
