Is it good for people under 18 year to have sex? And why?

It is generally not recommended for individuals under the age of 18 to engage in sexual activity. This is because young people may not be emotionally or mentally prepared for the potential consequences of sex, such as pregnancy, sexually transmitted infections, and the emotional impact of intimate relationships. Additionally, laws in many countries prohibit individuals under the age of 18 from engaging in sexual activity, and it is important to respect and adhere to these laws. It is important for young people to have access to comprehensive sex education and resources to make informed decisions about their sexual health and well-being.
