You ask a very interesting question without simple answers.
First, I assume you’ve never had a cold sore on your lip or nose, correct? The most common presentation of HSV 1 is a cold sore in one of those locations. About half the US population is infected with HSV 1.
Second, a positive HSV 1 antibody test that is accurate, and a high number here is almost always accurate, means that you are infected and potentially infectious to others. It means way more than being exposed.
Since you have no symptoms either orally or genitally, it is not possible to know the location of your infection, but if you ever get a symptom either orally or genitally, you need to have it swab tested to see if it is HSV 1.
Whether you need to disclose your HSV 1 status is the subject of much discussion, and I don’t think there is a perfect answer, and not even experts agree fully.
I recommend that you disclose your status (I have the cold sore virus) before giving oral sex to anyone, as the oral infection is more likely than genital. If you do have this genitally, it is rarely shed and unlikely to be transmitted via intercourse after you’ve been infected for a while.
There is no perfect answer here, I’m afraid.
