1 in 4 women and 1 in 5 men have genital herpes; of those 90% don't even know it, due to non-recognizable or no symptoms.
Anyone can find out their herpes status - request an "IgG type specific blood test" to find out your herpes status. Require it from any future sexual partners as well.
unless you get symptoms they are unlikely to test you for it. also, anxiety and stress (panicking about whether you have it) can trigger symptoms so as you dont have any, i would guess you have been lucky.
