In your specific circumstances, I don't think you have anything to worry about. Once your partner has HSV-2 you can't give it to him again, nor can he give it to you. I'm not familiar with 'different
strainsStrains ' of HSV-2. Anybody with herpes, oral or genital, can have periods where there are a cluster of outbreaks, for no particular reason. I would expect that you should revert to your old pattern.
Pep with HSV-2 shed virus in low titers between outbreaks. Maybe former partners got lucky, or maybe they contracted it and the virus remained latent, or maybe they got outbreaks after you lost touch with them. Going forward, you should be sure to have any non-HSV-2 partners be sure to use condoms, which is the best you can do to prevent infecting someone else. But you needn't worry about your current partner, either for yourself or for him.
Take care.
