Yes, it is possible for a person with HSV-1 (oral herpes) to transmit HSV-2 (genital herpes) by performing oral sex on another person. However, the same person would not develop HSV-2 themselves unless they were also exposed to and infected with that specific virus strain through sexual contact or other means. It's important for individuals who engage in any form of intimate activity to communicate openly about their STI status and use protection consistently to reduce the risk of transmission.
