Sexually transmitted diseases (STDs) are infections that are transmitted from one person to another through sexual contact. STDs can be caused by bacteria, viruses, or parasites. Here are two examples of STDs:

• Gonorrhea: This is an STD caused by bacteria. It can infect both men and women and can cause pain or discharge from the genitals.

• Genital herpes: This is an STD caused by a virus. It can cause painful sores or blisters on or around the genitals or mouth.

It is important to note that many STDs do not cause symptoms, so it is possible to have an infection and not know it. This is why regular testing is important for sexually active individuals.
