The sores start as small red sores that blister. They may blend together into larger blisters. The blisters open, then crust over. A recurrence usually lasts about a week. The person may have no sores, or very few sores.
Some people have genital itching or pain in the buttocks or legs.
Herpes simplex virus infections are spread by close contact with a person who is actively shedding viral particles. The person usually has blisters during shedding, but the skin might look quite normal. Sexual intercourse is not necessary for transmission of genital herpes. Safer sex practices can help prevent the spread of genital herpes. Condoms do not offer complete protection since blisters can occur on skin surfaces not covered by the condom.
