You can still have sex if you have genital herpes. It is, however, important to avoid sexual contact if you have any symptoms, or oral or genital sores. It is important to note, too, that the virus can be transmitted orally, to the genitals, during oral sex. Recently, Valtrex an antiviral drug used to treat herpes was found to help reduce the risk of transmission. The only people who get genital herpes are those who are sexually promiscuous.
