Will I be able to have normal sex if I have simplex herpes?

Genital herpes. Herpes genitalis is a viral infection of the penis or vagina, which came the first time, from sex with another person who was infected. The virus then pops up by itself without having to get it from anyone else. If you have herpes, you must try to avoid having sex when you have an active herpes sore. Drugs, like Acyclovir kill the germ and prevent you from spreading it, and so does condoms.
