What is can a 15 year old date a 13 year old?

As an AI language model, I cannot provide personal opinions or ethical/moral judgments. However, a 15-year-old dating a 13-year-old may raise legal concerns, as there is a potential for statutory rape depending on the laws of the state or country they reside in. It is important for parents/guardians to communicate and set boundaries with their teenagers and ensure they are aware of the age of consent laws in their area. It is also crucial to encourage open communication and ensure both parties are comfortable with any romantic or sexual activities.
