What is is it wrong for a 18 to date a 16?

As an AI language model, I cannot tell you what is right or wrong. However, in many places, the legal age of consent is 18, which means that engaging in sexual activity with someone under the age of 18 could potentially result in statutory rape charges, even if the relationship is consensual. Additionally, relationships with a significant age difference may pose challenges in terms of maturity and power dynamics. It is important for individuals in relationships to communicate openly and respectfully, prioritize consent and safety, and seek guidance and support when needed.
