5 Reasons Why Sex Causes UTI And 8 Holistic Ways To Heal

Sex causes UTI, STDs, babies, and orgasms. What a mess! But Let’s start with UTI.

E. coli bacteria cause more than 80% of all urinary tract infections. Surprisingly, E. coli reside in your lower intestines.

To put it simply: your poop is full of E.coli and there are always some bacteria around your anus.

Most E. coli are harmless and are an important part of a healthy human intestinal tract. For one thing, they help to produce vitamin K.

However, E. coli can cause serious damage to your health when it leaves its rightful place in your intestinal tract. How does this happen?

Sex should not cause a UTI

Before we dive into mechanics of E.coli transmission, I’d like to make an important segway.

If you are healthy, sex should not trigger a UTI.

If sex causes UTI, find out why. Look for an underlying condition that weakened you in the first place and allowed the UTI to develop.

Sex is not a cause for UTI. Sex is a risk factor. 

If you keep getting UTIs after sex, it is more important to address the main cause of your UTIs. For most women, sex causes a UTI if they have weakened vaginal flora.

How sex causes UTI

If you already have weakened vaginal flora, It is pretty easy to get a urinary tract infection (UTI) during sex

Any activity that brings bacteria in contact with the genitals and urethra can cause a UTI. Sex can sometimes cause a UTI because during sex there is a higher chance for bacteria to enter your urethra and vagina, due to its close proximity to your anus.

Consider this joke that illustrates the point:

Three engineers are discussing what kind of an engineer God is.

A mechanical engineer says: “God must be a mechanical engineer, look at all the complex mechanisms of the body!”

An electric engineer argues: “No, he must be an electrical engineer! Humans operate due to electric impulses from the brain!”

A civil engineer concludes: “From what I know, God is definitely not a civil engineer: why did he put a waste line near the recreational area?”

#1 Bacteria move from your anus to your vagina

There are always bacteria around your anus no matter how clean you are.

During sex, bacteria can move around due to the sheer force of the action involved and make their way to the vagina.

#2 Imbalanced vaginal flora allows bacteria to grow

If your vaginal flora is not healthy enough to expel the invaders, the E. coli will grow and multiply in the vagina.

If later you are sexually active again, some of the vaginal discharge containing the pathogenic bacteria could be moved up toward the urethra opening.

#3 E. coli ascends to the urethra

If E. coli find their way to the urethra, they will eventually move up toward the bladder, where the conditions for bacterial growth are perfect.

E. coli bacteria will attach themselves to the bladder lining and will start to multiply rapidly. Next thing you know, it is painful to pee, there is blood in your urine, and you are feeling crappy.

Anal play (including unprotected anal intercourse) is one of the factors guaranteed to increase your exposure to E. coli.

Even though contracting a UTI from sex is not normally a concern for men, if they engage in anal sex it is better to use a condom.

#4 Contraception increases your chances to contract a UTI

This being said, if you are using condoms with spermicide (or any other Nonoxynol-9 contraception products) for vaginal sex, your vagina’s normal microbial balance could change for the worse.

There are several factors that could predispose you to UTI after sex:

This could also happen if you are stressing out, taking hormones, or have just finished a cycle of antibiotics—they kill all bacteria, good and bad, throwing your vaginal flora out of balance.

All these factors may adversely impact the ability of your vagina to ward off E. coli. The more E. coli colonizes your vagina, the easier for the bacteria to get to your urethra.

#5 Other UTI risk factors

Sex increases the chances of contracting a UTI, but also all kinds of other things do, too. If you are not sure how you got your UTI, check out 25 main UTI causes that you should know.

Because bacteria can easily find their way into the urethra, it’s very common for women to have UTIs without knowing the real cause.

Sometimes the urethra gets irritated by sexual activity and you might then get urinary symptoms like frequency, urgency, and burning while urinating. This is called honeymoon cystitis, which is a misleading term. In reality, this should be called “honeymoon urethritis”.

In this case, the symptoms are not caused by bacteria or STDs, but by overstimulation and are gone in couple days.

If you repeatedly experience these symptoms and your urine sample is clean, use a lubricant and make sure your partner is gentle during sex and takes good care of their nails.

How E. coli Can Travel To Your Urethra

It’s pretty natural for E.coli to ascend toward your urethra, but some habits could further promote infection with the pathogenic bacteria:

  • Wiping from back to front: The more you expose your genitals to fecal matter (poop!) the higher the chances to infect yourself
  • Toilet water backsplash
  • Using bidet that sprays water from back to front. Use the one with a de-attachable handle instead
  • Wearing thongs: Some believe that wearing thongs would promote spreading bacteria from your anus toward your vaginal opening.
  • Lastly, UTIs can also be caused by sexually transmitted diseases (STDs). When a UTI is caused by an STD, the infection is most often only in the urethra, not the bladder. However, the symptoms could feel the same way.

In closing, remember:

  • E. coli is a part of normal bacterial flora in our intestines, rectum, and human poop.
  • It is easy for E. coli to travel to your vaginal opening. From there, especially during sex-play, E.coli could travel toward your urethra.
  • E. coli normally cannot survive in the healthy vagina for too long (too acidic for its taste). But they feel perfectly fine residing in the urethra and bladder.
  • Use special probiotics to keep your vagina healthy.

8 Holistic Strategies To Heal And Stop UTI Forever

Chronic UTI is a very misleading diagnosis. Most likely, you need to look for something else that allows for UTI to happened.

  1. Uncover true UTI cause
  2. Heal your bladder
  3. Fight bacterial biofilms
  4. Restore healthy gut flora with probiotics
  5. Improve your diet with a variety of fiber and prebiotics
  6. Improve your vaginal flora
  7. Heal your vagina
  8. Improve emotional health

    Hi. Recently, I fingered my girlfriend. And the next day she said she checked for UTI. But before I touched her, I washed my hands. Soap and water. I’m concern. Cause again I washed my hands.

    1. Hi Freddie, check this post, it might help to bridge the gap (even though it’s about oral sex, but it repeats the message about the importance of healthy vaginal flora. If she has misbalance vaginal flora, it doesn’t matter if your hands are clean, the bacteria are already in her vagina and then are just pushed further up toward urethra.

  2. Hello,
    Thank you for your post. I’m concerned I may get a UTI and I was wondering if you can get one by rubbing a penis between the butt cheeks (while on top of the male and not deep enough to touch the anus) and then rubbing the penis on the clitoris.

  3. Why don’t you mention the role of an asymptomatic male putting his urethra into your body? Because that’s what happens when you have sex; his genital passage and urethra are one. And he’s giving you a good dose of his germs every time. Treat him, you might find yourself better off too!

    1. Hi Michelle,
      Thank you for your comment. Funny, but men in most cases do not have bacteria causing UTI in their urethra (the only exception would be unprotected anal sex). Men do have other bacteria of course, but research in microbiota shows that their genital flora is much more influenced by ours rather than other way around. So unless he has an acute UTI, he would not contribute to our problem other than mechanically moving our own bacteria around 🙂

  4. Do you still get utis after using these preventative measures? I have a recurring uti problem ever since I became sexually active. Never had them before. Now I got about 6 or 7 this past year! Doctor is recommending I take a small dose of antibiotic every time after I have sex. Have you heard about this method? Thoughts? I’m not sure how I feel about it…

    1. Hi Ashley,
      No, I am not getting UTIs anymore (knock on wood). Yes, I’m familiar with this recommendation (you can read “About me”). If your UTIs are caused by sex, probiotics and D-Mannose combo might be helpful to supplement your prevention strategy. I believe this is what helped me. Best of luck!
