If you have a herpes outbreak (assumed to be referring to HSV-2), it is recommended that you wait until the sores or lesions are fully healed before engaging in sexual activity again. This typically takes around 7-10 days for the initial outbreak, but can vary from person to person. It's important to also consider your comfort level and any pain during this time. Additionally, using protection like condoms can help reduce the risk of transmitting herpes even when there are no visible symptoms present.
