Herpes Simplex 2 is caused by skin to skin, sexual contact.
It is exchanged through semen, bodily fluids, and exchange of saliva. If you, or your partner have herpes, it can be spread to each other during sex. Even when there is no signs of blisters, the area can “shed” the virus. Discuss with your doctor, and your partner ways of not spreading the disease.
Oral herpes (HSV1) can be spread to a partner during oral sex. This will result in your partner getting genital herpes (HSV2). To avoid this, refrain while blisters are present.
