If both you and your partner have type 2 genital herpes, it is possible to spread the virus back and forth between each other through sexual contact. During an outbreak of genital herpes sores (blisters), it's recommended to avoid sexual activity with your partner until the lesions are fully healed to reduce the risk of transmission.
Using protection like condoms can help lower but not eliminate this risk entirely. It's essential that you communicate openly with your partner about any symptoms or outbreaks so appropriate precautions can be taken together.
Consulting a healthcare provider for personalized advice on managing and reducing the transmission risks associated with genital herpes in a relationship is highly recommended.
