Why Does Your Vagina Burn After You Have Sex?

Feminine Story Banner

The skin in and around your vagina is extremely sensitive, and sex, though usually enjoyable, can become painful or cause irritation down there. There are a number of reasons you could be experiencing vaginal burning, particularly after sex. We’ve covered some of them below, and provided advice on how to reduce this uncomfortable sensation. 

 

Why does my vagina burn after I have sex?

A woman’s vagina contains a balance of ‘good’ and ‘bad’ bacteria. This balance can be determined by the pH level of the vagina. Sex and semen can alter the pH balance of the vagina which can sometimes result in itchiness, burning or irritation, particularly during or after sex. There are other reasons you may be experiencing vaginal burning, such as allergies or a fungal infection.

 

Urinary tract infection (UTI)

A UTI, otherwise known as a water infection, can cause irritation during sex. This infection is caused by bacteria that has built up in the urinary tract and causes it to become inflamed. Other symptoms can include a burning sensation when you wee and urine that is cloudy or has a slight pink/red tinge to it. UTIs can be treated with antibiotics. If you think you have a water infection, see your doctor.

 

Sexually transmitted infections (STIs)

Some STIs, such as Chlamydia, Herpes or Trichomoniasis, can cause burning during or after sex. These vaginal infections are fairly common, so if you’ve recently had unprotected sex, you should get tested. Most of them can be treated with a course of antibiotics, however, there isn’t currently a cure for herpes.

Symptoms of these STIs could include:

●     Itching or swelling

●     Unusual bleeding

●     Unusual discharge that’s an odd colour or texture

●     Pain in the lower tummy

 

Semen allergy

If you’re experiencing burning after sex, you may have an allergy to your partner’s semen. This is surprisingly common, as semen contains protein that can trigger allergy symptoms. These symptoms might include:

●     Redness

●     Swelling

●     Burning

●     Itching

●     Hives or sores

These symptoms could last for any period of time, from a couple of hours up to a couple of days. You can experience an allergic reaction in any area that has come into contact with the semen. If you think you may be allergic to your partner’s sperm, there are some steps that you could take to reduce your symptoms.

You could try using a condom if you don’t already, as this will prevent the sperm from touching the skin in your vagina. You could also try taking an antihistamine before sexual intercourse. If your symptoms persist or you think they’re getting worse, book an appointment with your doctor.

 

Hormones

The female body is complicated, and hormones play a big part in your overall health. If your oestrogen levels are low, you may be experiencing vaginal dryness?, which can be a cause of burning during sex. If your body isn’t producing enough oestrogen, you may also experience hot flashes, frequent UTIs or tender breasts. A doctor may be able to suggest some ways you can increase your body’s oestrogen levels.

 

Why is my vagina burning during sex?

Lack of lubrication

Lubrication is extremely important during sexual intercourse, particularly for women. Without enough lubrication, sex can become painful and may irritate the vagina. It could even lead to vaginal bleeding that’s caused by small tears in the skin when there’s too much friction occurring. During sex, you should always make sure that there’s enough lubrication. If you naturally aren’t producing enough, you can use a water-soluble lubricant. Avoid using scented lubrication as this can lead to further vaginal problems and irritation.

 

Too vigorous penetration

Burning during sex can suggest that the intercourse is too rough. Vigorous penetration can cause a large amount of friction which is why it may burn. You should let you partner know if it’s too rough or fast so you can find a speed that you’re both happy with that’s still enjoyable.

 

Allergic reactions

Your vagina is one of the most sensitive parts of your body. Because of this, you may experience allergic reactions to things that you weren’t aware you were allergic to. This could include condoms (latex), lubrication or toys. If you think you’re experiencing an allergic reaction during sex, have a think about the products you’re using and try to avoid them in the future.

You should try to avoid over-scented products, and instead choose a water-soluble lube that will be more gentle on your skin. If you think condoms are the issue, you could try some latex-free varieties or have a think about other forms of contraception that you could try.

 

Why does it burn when I pee after sex?

If the vagina has torn slightly during sex, then urinating afterwards can be a little bit painful and may burn slightly. Burning when you urinate after sex could also be due to any of the conditions that we’ve mentioned above.

 

If you have any other symptoms that are accompanying the burning, then you should book an appointment with your doctor.
