Are condoms out of style? Your body thinks otherwise.

Sexually transmitted infections are on the rise—and it’s not because we’re having more sex. It’s because fewer and fewer people are using protection during sex. Many people view condoms as a hassle, old-fashioned, or something that undermines trust. But what happens to the body when protection is removed—hardly anyone talks about that openly.

What exactly are sexually transmitted infections?

In short: infections that are passed on during sex. The most well-known are chlamydia, gonorrhea, syphilis, and genital herpes. What many people don’t know: most of these cause no or very few symptoms at first. You don’t notice anything—but you’re still passing the infection on.

The numbers speak for themselves

Case numbers are rising sharply across Europe. Gonorrhea, for example, was reported more than three times as frequently in 2023 as in 2016. And those are just the recorded cases—many infections go undetected because those affected have no symptoms and don’t get tested.

How can I tell if I have an infection?

The tricky part: often, there are no symptoms at all. Sometimes there is discharge, a burning sensation when urinating, a rash, or sores in the genital area—but frequently, everything remains asymptomatic. That’s why regular testing is so important, especially if you have multiple sexual partners.

What happens if an STI isn’t treated?

  • Chlamydia can lead to infertility if left untreated.
  • Syphilis can affect internal organs—the heart, liver, even the brain.
  • Gonorrhea is becoming increasingly resistant to antibiotics, making treatment more difficult.

In short: What sounds harmless can have serious long-term consequences.

And what about herpes?

Genital herpes is widespread—and incurable. The virus remains in the body for life and can flare up again and again. Here, too, transmission is often possible even if you don’t have any symptoms yourself.

What really protects you?

The condom. No other contraceptive protects against sexually transmitted infections. The pill, the IUD, the ring—they protect against pregnancy, but not against infections. Anyone who doesn’t use condoms is taking a real risk—even in a committed relationship, if neither partner has been tested.

Getting tested isn’t a sign of mistrust

An STI test isn’t an accusation against your partner. It’s simply a responsible choice—just like going to the dentist or getting a blood test. You can get tested discreetly and without shame at a urologist’s or gynecologist’s office. Often, a urine sample or a swab is all that’s needed.

The most important points at a glance

  • Use condoms—always, even with new partners.
  • Get tested regularly if you have multiple sexual partners.
  • No symptoms does not mean no infection.
  • Talking about safe sex is not embarrassing—it’s self-respect.

Your body belongs to you. Protect it.
