Why STIs Can Still Occur Despite Safer Sex

Safe sex can still lead to STIs is a situation that surprises many people. Not a few people believe that using condoms can completely eliminate the risk of contracting sexually transmitted infections (STIs). However, in reality, although safe sex significantly reduces the risk of infection, there are still some cases that can lead to infection. Understanding the limitations of protective measures will help each person be more proactive in caring for their sexual health and preventing potential risks.

What is safe sex?

Safe sex refers to the use of measures to reduce the risk of HIV and sexually transmitted infections (STIs).

Common measures include:

• Correct use of condoms
• Using PrEP for HIV prevention
• Regular sexual health testing
• Limiting high-risk behaviors
• Actively discussing health status with partners

However, no method provides 100% protection.

Why can safe sex still lead to STIs?

Some STIs spread through skin contact

Many people think that all STIs spread through semen or bodily fluids. In reality, some infections can spread through direct skin contact.

Examples include:

• HPV (genital warts)
• Genital herpes (HSV)

These viruses can exist on skin areas not covered by condoms. Therefore, the risk of infection can still occur even with condom use.

Oral sex still carries STI risks

Oral sex is often seen as less risky, but it is not entirely safe.

Some infections that can be transmitted through oral sex include:

• Throat gonorrhea
• Syphilis
• Herpes
• HPV
• Chlamydia

Many cases of infection in the mouth or throat do not show clear symptoms, making it difficult for patients to recognize.

Incorrect use of condoms

Condoms only work effectively when used correctly.

The risk of infection can increase if:

• The condom is torn or slips off
• The condom is not put on at the right time
• Condoms are not changed when switching sexual activities
• Low-quality condoms are used

Small mistakes during use can reduce the effectiveness of protection.

Many infections show no symptoms

One of the reasons many people are careless is because there are no obvious symptoms.

Infections such as:

• HIV
• Syphilis
• Chlamydia
• Gonorrhea

can exist in the body for weeks or months without causing clear symptoms.

Therefore, feeling healthy does not mean you are not infected.

Which infections can still spread even with safe sex?

HPV (Genital Warts)

HPV is one of the most common STIs today.

The virus can spread through:

• Skin-to-skin contact
• Sexual activity
• Oral sex

Some strains of HPV are also associated with the risk of cervical, anal, or throat cancer.

Genital Herpes

Herpes can spread even when the person carrying the virus does not have clear symptoms.

The HSV virus often spreads through:

• Direct contact with infected skin
• Kissing
• Oral sex
• Sexual activity

Syphilis

Syphilis sores can appear on the genitalia, anus, or mouth.

If direct contact with these sores occurs, the risk of infection can still happen.

How to reduce the risk of STIs?

Although it is not possible to completely eliminate the risk, you can significantly reduce the risk of infection by:

Correctly using condoms

This remains one of the most effective measures to reduce the risk of STIs and HIV.

Regular testing

If you are in a high-risk group or have multiple partners, it is advisable to test your sexual health every 3–6 months.

Vaccination

Vaccines such as:

• HPV
• Hepatitis B

help reduce the risk of dangerous diseases related to sexual health.

Using PrEP when at risk of HIV

PrEP is an effective HIV prevention method that can reduce the risk of HIV transmission through sexual activity when used correctly.

Actively discussing with partners

Sharing health information and test history helps both partners make safer decisions.
