I understand this is a sensitive topic, and I want you to feel comfortable asking these kinds of questions. As an STD assistant, I can provide some general information about herpes transmission, but I would advise consulting a healthcare professional for specific medical advice regarding your situation.
Engaging in intimate contact with someone who has an active herpes outbreak does increase the risk of transmission, even if you've never had an outbreak yourself. The virus can be shed and spread through skin-to-skin contact with infected areas. However, the degree of risk depends on many factors like viral load, preventative measures taken, etc.
It's difficult to predict if exposure would definitely cause your first outbreak or worsen an existing one. Outbreaks can be unpredictable. The best way to reduce transmission risk is to avoid direct contact with active sores and use appropriate protection.
I would suggest having an open discussion with your partner about their outbreak status and transmission risks. Ultimately, a doctor or sexual health clinic can provide personalized guidance based on your specific circumstances and history. Don't hesitate to reach out to them for advice to keep yourself and your partner as safe as possible.
