It sounds like you are really focused on herpes. That’s three sexual encounters that you’ve described over a period of more than a year (there could have been others but I think you would have told me) and each time, you believe that you’ve likely contracted herpes. I don’t think so. None of this sounds anything like herpes to me and I”m so glad that you arranged a western blot to know that you don’t have HSV 2. The HSV 1 could be either oral or genital but with the brief encounters, I’m thinking maybe oral. Have you ever in your life had a cold sore on your lip?
Men who still have a foreskin are far more vulnerable to acquiring bacterial and fungal infections and my guess is that the bumps are likely related to one of those two things rather than herpes. The bumps you describe just don’t fit with herpes. They do sound, on other parts of your body, like clear folliculitis.
The odds of getting herpes at a single encounter are very low to start with and you are adding to that low risk for wisely using condoms. So in my mind, your risk of acquiring HSV 2 is really low. And we know you already have HSV1 (though we don’t know if the bumps are HSV 1).
The research suggests that people rarely get another strain of the same type (1 or 2).
