No, if a person without herpes has oral sex with someone who has HSV-2 (genital herpes), they are at risk of getting HSV-1. However, the transmission from genital to oral is less common compared to direct contact during sexual activity involving genitals or mouth. It's essential for individuals engaging in any form of intimate contact to communicate openly about their STI status and take necessary precautions like using condoms and dental dams consistently to reduce the risk of transmission.
