The answer is yes. Yes, but In women, urinary tract infections often occur after sex. But a bladder infection isn’t contagious. So why does sex cause a bladder infection? We’ll help you see more clearly.Sexy Woman

Cystitis is a urinary tract infection that is characterized by a burning sensation when you urinate.

However, a urinary tract infection is not sexually transmitted. If you have sex with your partner and he or she has a urinary tract infection, there is no danger – a bladder infection is not contagious.

What is a urinary tract infection?

In most cases, cystitis is caused by a bacterium called Escherichia coli, which occurs naturally in the bowel. This bacterium is not contagious. It also does not survive outside. So Escherichia coli is not passed from person to person.

It is, however, possible to contaminate oneself. In other words, bacteria in the intestines can enter the urinary tract after sexual intercourse and migrate.

Why does post-coital cystitis occur?

The urinary tract, vagina and anus are very close together. In addition, a woman’s urethra is short – about 2, 3 or even at most 4 cm. Because the urethra and anus are so close together, germs can easily move from one opening to another and cause urinary tract infections.

So it is not the partner who infects the woman. Rather, it is the movement of the penis inside the vagina that helps the germs to travel from the outside to the inside of the vagina and cause an infection.

And this proximity helps the bacteria to get from the anus into the vagina, which is supported by the movement of the tongue, penis and/or fingers.

The resumption of sexual activity promotes the development of cystitis.



Are you having sex frequently again after a long period of abstinence? Then you are more likely to develop a urinary tract infection. Very frequent sexual intercourse (honeymoon syndrome) can also cause cystitis, as sex causes irritation and promotes infections.

If you have a new partner, you are also more likely to develop urinary tract infections. This is because your body is not yet accustomed to the bacteria that your new lover carries.

Can you make love during a urinary tract infection?

A urinary tract infection is not contagious. So there are no contraindications for sex during a bladder infection. However, sex can be very uncomfortable with a urinary tract infection, as it can make certain symptoms more painful and intense. It is best to treat yourself before resuming sexual activity.

How can you avoid urinary tract infections after sex?

Of course there are some simple things you can do to avoid post-coital urinary tract infections:

Urinate immediately after intercourse.

When urine comes out, it “washes” the urethra, kills germs and prevents them from going up to the bladder.

Drink plenty of water

Water dilutes the urine. Do not hesitate to drink plenty of water every day, preferably in small sips.

Take a food supplement

D-mannose is a simple sugar, a cousin of glucose. It coats the cells of the urinary tract. It’s found in certain fruits: peaches, apples, blueberries, or oranges. D-mannose cures cystitis naturally.

Cranberry products are also known to help.

The limit of natural remedies: they do not cause resistance as antibiotics can. However, it is important to note that food supplements are not medicines and that a health professional should be consulted in order to act effectively.

Cleaning up after sexual intercourse

Finally, intimate washing after sex can help to reduce the risk of cystitis. Namely: a lack of hygiene promotes the growth of bacteria. However, excessive hygiene is also destructive to the vaginal flora that protects the vulva.
