Yes every single one of us has herpes - there are many different strains of it - I remember seeing a scientific study a long time ago that showed something crazy like 90% of children age 1 had contracted it (you get it by putting things into your mouth and so forth) - however, most of us never realise we have herpes because our immune system suppresses outbreaks of it - that is why when the weather is cold and people get sick, their immune system is lowered which is why they have outbreaks
Genital herpes (HSV2) is a different strain to the strain we all have (HSV1)- the virus integrates it’s DNA into your DNA so once you got it, you have it for good
In my opinion - you have broken up once before - whats to say it’s not going to happen again? And if you catch HSV2, well could you like with the guilt having sex with someone else knowing you could possibly be infecting them?
