A more thorough explanation:

Venereal disease, also known as sexually transmitted disease (STD), is a disease that is transmitted through sexual contact with an infected person. Common examples of STDs include syphilis and gonorrhea.

For example, if someone has unprotected sex with a partner who has syphilis, they can contract the disease. Similarly, if someone has unprotected sex with a partner who has gonorrhea, they can also become infected.

It is important to practice safe sex and get tested regularly for STDs to prevent the spread of these diseases and protect your own health.
