Genital herpes is a common sexually-transmitted infection that affects over 1 in 5 adults worldwide. Symptoms of genital herpes typically include painful blisters on the genitals, bottom, and thighs, which can show up in the area that full briefs or boxer shorts would cover.

In this guide, you’ll learn about the early signs of genital herpes, including different symptoms in men and women. We’ll also explain the difference between primary and repeat genital herpes outbreaks, as well as treatment methods and other ways you can manage your symptoms.

What is genital herpes?

Genital herpes is an infection of the genitals caused by the herpes simplex virus (HSV). There are two forms of HSV that can affect the genitals, HSV-1 and HSV-2. Both can cause typical symptoms of genital herpes like sores and blisters, and HSV-1 tends to cause cold sores in the mouth too.

What causes genital herpes symptoms?

Genital herpes symptoms are caused by either a first-time infection or a repeat outbreak.

Symptoms of genital herpes appear if you’ve been exposed to the HSV , either through direct contact with blisters, infected sexual fluids, or infected skin. This is mostly through sexual contact, such as penetrative sex, oral sex, or sharing sex toys. You can also spread herpes if you rub infected skin or eyes and touch another part of your body or another person’s body.

The first signs of genital herpes can show up anywhere between a few days to a few months, or even years after initial exposure to HSV.

Repeat outbreaks can happen any time after the first infection and cause symptoms to come back.

Will it be obvious if you have genital herpes?

Although HSV is a very common and contagious virus that can cause blisters and other symptoms, most people with genital herpes do not know they have it.

Only 1 in 3 people with the virus ever develop symptoms, and 2 out of 3 people have such mild symptoms of genital herpes that they’re unaware they have it at all. Additionally, HSV can be spread when there are no visible symptoms, a concept known as asymptomatic shedding. This is what makes the herpes simplex virus so common among sexually-active adults.

With HSV, you will not have genital herpes symptoms all the time. This is because the virus sleeps (lays dormant) in your nerves until something happens that triggers an infection. Then you will start to get symptoms and may feel unwell. You’re more likely to spread herpes when you have sores or blisters that you can see, than when you are not experiencing symptoms. However, keep in mind that you can still spread the virus even if you do not have symptoms that you can feel or are visible. Antiviral treatments can help you prevent and manage an outbreak, and you should always communicate your sexual history to a new partner to be safe.

What are the initial signs of genital herpes?

The early signs of genital herpes you need to look out for are:

  • a skin rash that develops within a week after unprotected sexual contact
  • blisters that burst to form erosions (red skin sores)
  • headache, fever, tiredness, pain passing urine, or tenderness underneath the skin

Other symptoms may include discharge, swelling or a tingling sensation in the genital area.

You may experience body aches, headaches and fever.

Note that herpes rash and lesions look different on different skin tones. If you are uncertain whether or not what you are experiencing is herpes, speak to your doctor.

Understanding your first outbreak

The genital herpes symptoms you might get after you first contract HSV are usually more uncomfortable and longer-lasting than symptoms from any repeat outbreaks afterwards. This is because it’s your body’s first ‘experience’ with the virus (known as primary infection), and your immune system needs to learn how to recognise and suppress HSV.

Your first genital herpes episode can last anywhere from 2 to 4 weeks, which is longer than a repeat herpes outbreak that typically lasts between 7 to 14 days.

If you do start to get symptoms, we recommend seeing a doctor straight away and getting tested. This is because herpes treatment is more effective when you start it early.

Signs of recurrent genital herpes

Signs of recurrent genital herpes are like your first ever outbreak but milder.

You may start to feel an infection coming on, such as tingling or burning in the genital area followed by bumps, blisters, and ulcers. Recurrent genital herpes symptoms tend to occur at a single site on the body on one side. Fever, aches, and tiredness are symptoms that are less common in recurrent genital herpes.

Symptoms of genital herpes in men and women

Though some herpes outbreak symptoms are the same for any sex or gender, there are specific differences in where and how the flare-ups occur.

What are the symptoms of genital herpes in men?

Symptoms of genital herpes in men include:

  • tingling in the genital area including the penis, scrotum, anus, bottom, or thighs
  • red bumps that form blisters
  • blisters that burst to form ulcers (deep skin wounds)

Please note: some symptoms of genital herpes inside the rectum can’t be seen or identified easily.

Early signs of genital herpes in men

Early signs of genital herpes in men may include some flu-like symptoms and you may have:

  • tingling, burning, or stinging around the genitals
  • swollen glands
  • headaches, tiredness, fever, and muscle aches
  • discomfort passing urine

What are the symptoms of genital herpes in women?

Symptoms of genital herpes include:

  • tingling in the labia, vagina, anus, bottom, or thighs
  • red bumps which form blisters
  • blisters which form ulcers (deep skin wounds)

Note: some symptoms of genital herpes inside the vagina or rectum may be more difficult to notice.

Early signs of genital herpes in women

Early signs of genital herpes in women may include mild flu-like illness, and you may have:

  • changed sensation in the genitals
  • swollen glands in the groin, neck, and armpits
  • aches in the body
  • difficulty or pain when passing urine

If you think you have any symptoms of genital herpes, you should speak to a doctor, and you may want to consider doing an at home genital herpes test or general STI test. A doctor can help confirm or rule out other conditions that may be causing you discomfort. They can recommend the right treatment for you and advise you on what your next steps should be.

How often can you get herpes outbreaks?

How often you get herpes outbreaks depends on many factors, such as which type of HSV virus you have and your triggers.

HSV-2 tends to cause an average of 4 to 5 outbreaks per year. The average for HSV-1 is less than 1 outbreak per year.

Herpes outbreaks occur more often in the first year after the first outbreak. After some time, you may find the symptoms you get are milder and happen less often as you get fewer outbreaks.

Genital herpes outbreaks can happen at random, or they can be caused by certain triggers, including:

Flu icon

Being ill or feeling run down

Illness or fatigue weakens your immune system, increasing the chance of an outbreak.

Burnout

Stress

Physical or emotional stress can ‘activate’ the virus.

Hands over genitals in pain

Friction or rubbing

Caused by sex, tight clothing, or physical activity that irritates the genital area.

Damage to skin

Injuries, surgery, or even shaving can trigger symptoms in affected areas.

Intense exposure to sunlight

Excess sun or use of sunbeds can lead to flare-ups, especially with HSV-1.

Icon illustration of dizziness

Smoking and alcohol

Smoking and drinking alcohol can weaken the immune system, making it less effective at combating viral infections like herpes. Alcohl can also increase inflammation which can trigger herpes outbreaks.

cream icon

Using steroid creams or tablets

Steroid medications may also suppress immune response, making outbreaks more likely.

virus icon

Weakened immune system

Immune suppression from illness or medications can allow the virus to reactivate.

Menstruation or hormonal changes

Hormonal fluctuations (e.g. periods, pregnancy, menopause) can sometimes trigger symptoms.

How long does a herpes outbreak last?

Symptoms of a herpes outbreak can last a few weeks, but you can lower this time by getting treatment as soon as possible. Repeat genital herpes flare-ups are usually much shorter than your first outbreak.

You may also hear herpes outbreaks referred to in ‘stages’. This refers to the cycle of the lesion development and healing.

Recurrent genital herpes outbreaks typically follow this timeline:

Days Stage

1-2

Prodrome symptoms (tingling/itching)

3–5

Redness, bumps, and blisters begin to form

5–7

Ulcers (open sores) that can release fluid

7–14

Sores scab over and begin to heal

Not everyone experiences each stage. It’s important to bear in mind that you can be infectious at every stage of an outbreak, even if there are no visible blisters.

Can you make a genital herpes outbreak shorter?

Yes, there are a number of medications and treatments that can help to reduce the length and severity of herpes outbreak symptoms, and even prevent outbreaks from occurring entirely.

You can also minimise your risk of outbreaks by avoiding and managing triggers where possible.

Treatment options for genital herpes

Genital herpes symptoms can sometimes be painful or uncomfortable. Although there is no permanent cure for HSV, there are several treatment options for genital herpes to help you manage your symptoms.

Antiviral creams and tablets are commonly prescribed to treat herpes. They’re most effective if you take them as soon as your herpes symptoms appear. You should start to feel better within a few days of starting a course of antiviral medicines. Examples of antivirals that can help treat genital herpes are:

Your doctor will tell you which treatment is most suitable for you based on the type of HSV you have, the severity of your symptoms, and whether it’s a first outbreak or not. They’ll also take any pre-existing health conditions and other medications into consideration, and determine the best course of action if you’re immunocompromised or pregnant.

Other ways to manage your herpes outbreaks include:

  • making lifestyle changes to avoid triggers, such as quitting smoking or cutting down on alcohol
  • using painkillers or numbing creams to help with discomfort
  • washing blisters carefully with salty water
  • wearing loose-fitting clothing
  • avoiding scented body wash or soap
  • abstaining from sex until all blisters have healed over completely

Conclusion: Genital herpes symptoms can be uncomfortable, but treatment is widely available

Although symptoms of genital herpes can be unpleasant, it helps to know that you’re not alone, and that outbreaks typically get less frequent and less severe over time. The key to living well with HSV is understanding your symptoms, managing your triggers, and getting the right treatment when you need it.

If you think you may have herpes, it’s a good idea to get tested. A proper diagnosis means you can access effective antiviral treatment, manage future outbreaks, and reduce the risk of passing the virus to a partner. You can absolutely have fulfilling relationships and a healthy sex life with HSV. Open, honest conversations with your partner, along with the right treatment plan, can help you live with HSV confidently.
