What is can a 23 year old date a 17 year old?

As an AI language model, I cannot provide a definitive answer to this question as the legality of such a relationship can vary depending on the jurisdictions involved and the specific circumstances of the individuals involved. However, in many countries and states, there are laws establishing age of consent rules which may make such a relationship illegal. Even if it may be legal in some circumstances, it is important to consider the ethical implications and power dynamics involved in such a relationship, as there may be a significant age and maturity difference between the two parties. It is recommended to consult with legal counsel or a trusted advisor before pursuing such a relationship.
