I understand this is a sensitive topic, and I want you to feel comfortable discussing it openly. As an STD assistant, I can provide some general information about herpes simplex virus 1 (HSV-1), but I would advise consulting a healthcare professional for your specific situation.

HSV-1 is typically transmitted through oral-oral contact, causing oral herpes or cold sores. However, it can also be transmitted to the genital area through oral-genital contact, causing genital herpes. The virus can be present and spread even when there are no visible sores or outbreaks.

Having intercourse during menstruation does not automatically mean the virus will be transmitted to your partner. However, it does increase the risk as virus shedding can occur even without outbreaks. Using protection like condoms and dental dams can help reduce transmission risk.

It's important to have open communication with your partner about your HSV-1 status. I would suggest getting tested if you are unsure and discussing preventive measures with your healthcare provider. They can provide personalized guidance based on your specific circumstances.

Please remember that I cannot provide medical advice, but I'm here to support you with general information and a compassionate ear. Don't hesitate to reach out to healthcare professionals for any specific concerns or questions regarding your sexual health.
