Sex is a natural and enjoyable part of life, but it also comes with risks that many people overlook. While most individuals focus on pregnancy prevention, the biggest sexual risk remains having unprotected sex with someone who has not been tested for sexually transmitted infections (STIs).

Even with protection like condoms, there are still diseases that can be transmitted—some with lifelong consequences. So, is trusting someone’s word enough? And are condoms alone a foolproof safeguard?

This article explores the risks and why a simple STI test might be the most important step in protecting your sexual health.

The Real Danger of Sleeping with an Untested Partner

Most STIs are silent, meaning they show no symptoms but can still be passed on. Some infections can linger for years, only being discovered when complications arise.

STIs That Can Be Passed On Without Symptoms:

• Chlamydia – The most common bacterial STI, often undetected in both men and women.
• Gonorrhoea – Can cause infertility if untreated.
• Human Papillomavirus (HPV) – Some strains cause cervical cancer or genital warts.
• Herpes (HSV-1 & HSV-2) – Can be transmitted even without visible sores.
• Syphilis – Early stages might show no symptoms but can cause serious long-term damage if left untreated.
• HIV – Many people remain asymptomatic for years, unknowingly passing it on.

Studies show that one in two sexually active people will contract an STI by the age of 25, many without ever knowing.

Are Condoms Enough to Prevent STIs?

While condoms are one of the best preventative tools, they are not 100% foolproof when it comes to STI protection.

How Effective Are Condoms?

• Highly effective against: HIV, gonorrhoea, chlamydia.
• Less effective against: Herpes, HPV, syphilis (if sores or lesions are outside the condom area).
• Ineffective if: There are breaks, tears, or incorrect usage.

The bottom line is that condoms reduce but do not eliminate the risk of STIs. If your partner is untested, you could still be exposed to infections that condoms do not fully protect against.

Why STI Testing Is More Important Than Just “Trust”

Many people assume they are STI-free just because they have no symptoms or because they were tested a long time ago. However, past results do not guarantee current status.

Common Myths About STI Testing:

• “They look clean, so they must be safe.”
  • Truth: Many STIs do not have visible symptoms.
• “They said they were tested a year ago, so they’re fine.”
  • Truth: A person can contract an STI at any point after their last test.
• “I trust them, so they wouldn’t lie.”
  • Truth: Even people with good intentions might not realise they are carrying an infection.

How Often Should You and Your Partner Get Tested?

Experts recommend testing if:

• You have a new sexual partner.
• You had sex without protection (even once).
• You or your partner had multiple partners in the past.
• You have any unusual symptoms (pain, discharge, sores).

How often should you test?

• Every three to six months if you are sexually active with multiple partners.
• Once a year for general check-ups.
• Immediately if you had unprotected sex.

Safe Sex Beyond Condoms: Best Practices

To fully protect yourself, consider these steps in addition to condoms:

• Ask for STI testing before sex – It is a normal and responsible conversation to have.
• Get tested together – Some clinics offer couples testing for added peace of mind.
• Use dental dams and condoms – Protection is not just for penetrative sex; oral and skin contact can transmit infections too.
• Limit high-risk behaviour – Reduce unprotected sex, especially with new or multiple partners.
• Know your partner’s history – Open communication is key.

The Consequences of Ignoring STI Testing

Ignoring STI testing does not just put you at risk—it endangers others too. Some STIs, if left untreated, can cause:

• Infertility (chlamydia, gonorrhoea).
• Chronic pain and complications (herpes, syphilis).
• Increased risk of HIV transmission (if other STIs are present).
• Cervical and throat cancers (HPV).

Many of these risks are preventable with regular testing and responsible sexual behaviour.

Final Thoughts: Is It Worth the Risk?

Sleeping with someone without an STI test is one of the biggest sexual risks you can take. Even with condoms, some infections can still be transmitted, making testing the safest option.

Instead of relying on assumptions, past tests, or trust, make STI screening a normal part of your sexual health routine. A simple test protects you, your partner, and your future.
