Some of the following factors may triggers genital herpes symptoms:
Sexual intercourse. Some people find that the friction of sexual intercourse irritates the skin and brings on symptoms. Using a water-based lubricant can help reduce irritation. Don't use one that contains the spermicide nonoxynol-9, however. Nonoxynol-9 can irritate mucous membranes, such as the lining of the vagina. Oil-based lubricants are a no-no, too. They weaken latex, making condoms more likely to break. Even if...
Most people with genital herpes don't know they have it. That's because in most people it produces either no symptoms or very mild ones.
What Happens in an HSV Infection?
Genital herpes virus is passed from one person to another through sexual contact. This happens even if the person with the virus doesn't have symptoms or signs of infection.
Once the virus enters through the skin, it travels along nerve paths. It may become dormant (inactive) in the nerves and remain there indefinitely.
From time to time, the virus may become active. When that happens, the virus travels back along the nerve path to the surface of the skin, where additional virus is shed.
At this point the virus may cause an outbreak of symptoms. Or it may remain undetected.
In either case, the active virus is easily passed from one partner to another through sexual contact. Even wearing a condom may not protect the uninfected partner. The virus can be present on skin that remains uncovered.
The number of recurrences or outbreaks a person can have may vary.
What Are the Symptoms of Genital Herpes?
Even though you can still pass the infection, you may never notice that you have symptoms from an HSV infection. On the other hand, you might notice symptoms within a few days to a couple of weeks after the initial contact. Or, you might not have an initial outbreak of symptoms until months or even years after becoming infected.
When symptoms occur soon after a person is infected, they tend to be severe. They may start as small blisters that eventually break open and produce raw, painful sores that scab and heal over within a few weeks. The blisters and sores may be accompanied by flu-like symptoms with fever and swollen lymph nodes.
