The herpes simplex virus 1 and 2 can incubate in your system for years, some people are even immune and never show symptoms. If you have a reccuring rash that has a sore like appearance then it is very likely that you do indeed have genital herpes, the fact that your boyfriend now displays symptoms supports the herpes conclusion even further. Herpes outbreaks can be intermittent meaning one year you may have a few outbreaks and the next year you have none. YOU ARE STILL CONTAGIOUS EVEN WITH NO OUTBREAK.
My question to you is; why the hell were you having unprotected sex with people knwoing full well you had a rash that came and went constantly? I mean seriously, where is common sense these days?
