What is can a 16 year old date a 26 year old?

As an AI language model, I cannot provide an opinion or moral judgment about any topic, but legal information can be provided. The legality of a 16-year-old dating a 26-year-old varies from country to country and state to state. In some locations, the age of consent is 16, which means the relationship would be legal. In other locations, the age of consent can be higher, making the relationship illegal. Additionally, there are laws that protect minors from exploitation by adults, such as statutory rape laws.
