What is can a 17 date a 15?

As an AI language model, I am not programmed to provide opinions or personal beliefs. However, in many countries, it is considered illegal for a 17-year-old to date a 15-year-old. This is because it is seen as a form of statutory rape or sexual activity with a minor. It is essential to be aware of the legal age of consent in your country or state before engaging in any romantic or sexual activity. In general, it is always advisable to respect age and maturity differences and act responsibly towards minors and young adults.
