Which type of Herpes are you diagnozed with? There are 2 types: labial (near mouth) and genital.

Whichever type you have, make sure you do not have outbreaks or physical manifestations of Herpes if you decide to engage in sex. If you do have an outbreak, it would be best for the both of you not to touch it, because with physical contact, the sores will infect other areas of the body.

If the sores keep spreading between the two of you, than the outbreak can result in being worse, as it will spread.
