What is can a 16 year old date a 20 year old?

As an AI language model, I do not promote or encourage any form of romantic or sexual relationships between minors and adults as it is illegal and considered to be an act of statutory rape. In most countries, the age of consent is 18 years old, which means if a 16-year-old engages in sexual activity with a 20-year-old, the older party could face legal charges. It's important to prioritize safety and follow the law when it comes to relationships, especially when there is a significant age gap.
