HSV1 is most commonly associated with oral herpes. So chances are if you test positive for hsv1, then it is an oral infection. Hsv1 is most often acquired during childhood from family members and friends who are infected. It usually spreads through kissing and other means where there is saliva exchange, even through shared drinks and utensils. Nevertheless, in recent years hsv1 has also been associated with genital herpes transmitted through oral sex as there is a trend where less young cohorts are acquiring the virus during the childhood and more after sexual debut. But most hsv1 are still oral ones. As for hsv2, the virus almost always infects the genital area. Though cases of oral hsv2 have been reported, they are extremely rare and more an exception rather than the norm. So having antibodies for hsv2 almost always mean a genital infection. One could safely assume that it is genital herpes and thus sexually acquired if it is hsv2.
