Sexually transmitted infections, often called STIs or STDs, are infections that can be passed on during sex. This can happen through vaginal sex, anal sex, oral sex or close contact between mucous membranes. Many teenagers feel scared or embarrassed when they hear the word “STD,” but the truth is that these infections are common and most of them can be treated. The important part is understanding how they spread and how you can protect yourself.

The most common STIs include chlamydia, gonorrhea, herpes, HPV and genital warts. Some infections cause noticeable symptoms like unusual discharge, burning, itching or blisters. Others have no symptoms at all, which means you might not know you have them. That’s why condoms are one of the best ways to protect yourself and others. Getting tested is another important part of caring for your body, especially if you’ve had unprotected sex or something feels different.

As a teenager, talking about sex and health can feel uncomfortable. Many worry about being judged or misunderstood. But getting tested isn’t a sign of experience or anything shameful. It’s simply a way of taking care of your health and respecting your body. It also shows respect for anyone you might be intimate with in the future.

And it’s always okay to say no to sex if you feel unsure. No one has the right to pressure you. Feeling safe is what matters most. Protection isn’t about mistrust — it’s about valuing yourself.
