there is no easy or definitive answer. expose to someone with active (visible fresh lesions) herpes the outbreak on the exposed person can be relatively fast. when genital herpes is dormant (no visible signs of the disease) the chance of exposure is considerably less but unfortunately not zero. many people who have contracted herpes were not aware that their partner was infected and ended up contracting it in this dormant stage so we do know that this virus can be shed even when lesions are not present.
how long does it take to show symtoms after having intercourse with someone who has genitle herpes? . also if they haven't had a outbreak in 5-10 years and show no signs of the disease can you still get it? lastly can you get the disease from oral sex if they have no symptoms?
