If both you and your partner have HSV-2 (genital herpes), it is generally safe to engage in oral sex. However, there are some considerations to keep in mind:

1. **HSV-2 Transmission:** While the risk of transmitting HSV-2 from genital-to-genital contact is higher than oral-to-genital or oral-to-anal transmission, there's still a possibility of spreading the virus during any sexual activity.

2. **Cold Sores (Oral Herpes):** If either you or your partner also has cold sores caused by HSV-1 on their mouth ("oral herpes"), this can potentially lead to cross-infection between sites if precautions aren't taken.

3. **Protective Measures:** Using barriers like dental dams or condoms for oral sex can reduce the risk of transmission further—it's always good practice even when both partners carry the same strain but may be infected at different locations.

4. **Communication:** Openly discussing concerns with each other and understanding potential risks helps maintain trust while taking necessary steps together towards safer intimacy without fear—remember that communication plays a vital role in maintaining healthy relationships despite an STD diagnosis.

While overall it may be deemed relatively "safe" based on shared infection status, proactive measures should still be undertaken considering individual health situations; consultation with healthcare providers would provide tailored advice best suited for personalized care.
