Genital Herpes is an STD caused by HSV-1 or HSV-2, although, mostly caused by HSV-2. Genital herpes is a contagious viral infection affecting primarily the genitals of men and women. Genital herpes is characterized by recurrent clusters of vesicles and lesions at the genital areas or below the waist. The female genital areas are on or near the pubis, vulva, labia, clitoris, buttocks or rectum.
The areas for male genital herpes include on or around the penis, the inner thigh, buttocks, or rectum. Proctitis, or inflammation of the rectum, can be due to HSV.
A person usually gets HSV-2 infection during sexual contact with someone who has a genital HSV-2 infection. Transmission may occur even if there is no visible outbreak if the infected person is shedding . 80 percent of people don't even know they have it. In the United States alone, there are about 500,000 new cases of genital herpes infections annually. While generally not dangerous, it is a nuisance and can be emotionally traumatic, as there is no cure.
The number of HSV-1 genital herpes infections is rising. It is no longer the rule that HSV-1 is above the waist. If you receive unprotected oral sex from someone infected with cold sores, you can contract HSV-1 on your genitals. Do not give oral sex if you have an active cold sore or if you are feeling the prodromal symptoms .
Antibodies that develop following an initial infection with a type of HSV prevents reinfection with the same virus type—a person with a history of orofacial infection caused by HSV-1 cannot contract herpes whitlow or a genital infection caused by HSV-1. [ citation needed ] In a monogamous couple, a seronegative female runs a greater than 30% per year risk of contracting an HSV infection from a seropositive male partner.  If an oral HSV-1 infection is contracted first, seroconversion will have occurred after 6 weeks to provide protective antibodies against a future genital HSV-1 infection. Herpes simplex is a double-stranded DNA virus . 
From here, however, the question of transmissibility gets more complicated. Acquisition of one type is more difficult-though certainly possible-if you already have the other type. This is because either type, contracted orally or genitally, causes the body to produce antibodies, some of which are active against both HSV-1 and 2. This acquired immune response gives some limited protection if the body encounters a second type. When a person with a prior HSV infection does contract the second type, the first episode tends to be less severe than when no prior antibodies are present.
