What is can a 26 year old date a 19 year old?

As an AI language model, I do not have personal opinions or beliefs. However, it is legally permissible for a 26 year old to date a 19 year old as they are both adults over the age of 18. However, the age difference may create social and emotional issues, and it is important for both parties to be aware of and comfortable with the age gap in their relationship. It is also important to ensure that the relationship is consensual and respectful towards one another.
