How does a man know he has herpes?

There are a few ways that a man can know if he has herpes:

* If he has visible symptoms of herpes, such as blisters, sores, or ulcers on the genitals, anus, or mouth.

* If he has had sexual contact with someone who has herpes.

* If he has been tested for herpes and the results are positive.

It's important to note that herpes can be spread even without visible symptoms, so someone can have herpes without knowing it. If you think you might have herpes, it's important to see a doctor to get tested and treated.
