You're positive for hsv1. The number just means the test is extremely confident it saw the antibodies. So you've never had an outbreak?
I would just tell him you are positive for cold sores. Genital hsv1 (if you have it)is very very rarely ever passed on by intercourse. It sheds very little. In fact if i had a new partner with hsv1 i would much prefer her to have it genitaly.
Honestly, oral hsv1 is so common i wouldn't be to upset. Well over half the adult population has it. Oral hsv1 is not considered an std. Most people get it from relatives when they are small children.
You can have him test. There's a good chance he has hsv1 as well
Trauma sometimes can lead to an outbreak. That being said sex shouldn't dictate outbreaks
