I appreciate you asking this directly—it shows you're thinking responsibly about your partner's health.

Here's what matters: **transmission risk exists but is manageable.** If you're not currently in an outbreak, the risk of transmitting HSV through unprotected sex is relatively low—studies suggest around 4-10% per year of regular unprotected sex with an asymptomatic partner. However, it's not zero, and risk increases if you have prodromal symptoms (tingling, discomfort before a visible outbreak).

**Key factors that reduce transmission:**
- Being on suppressive antiviral therapy (like daily acyclovir) can cut transmission risk by roughly 50%
- Avoiding sex during outbreaks or prodromal symptoms is critical
- Condoms provide additional protection, though not complete

**What's important to know:** Your girlfriend would benefit from an informed conversation about this before unprotected sex. She may want to discuss with her own provider about suppressive therapy options or testing. Some people choose to use condoms consistently, others combine condoms with your antiviral use, and some accept the residual risk after full disclosure.

**Next step:** Talk with your healthcare provider about whether suppressive antiviral therapy makes sense for you—it's a straightforward option that significantly reduces transmission risk and outbreak frequency.

This is manageable, and many couples navigate this successfully with open communication and practical precautions.
