After an outbreak of herpes, it is recommended to wait until the lesions have disappeared before engaging in sexual activity. This is because the risk of contagion is much lower at that point. Also, keep in mind that herpes is a lifelong virus that you carry, and there are different strains of the virus that could potentially infect you. It is important to be cautious with contact, as the virus can easily be transmitted through close contact, which could potentially trigger another outbreak.
