What is can a 17 date a 19?

Yes, a 17-year-old can date a 19-year-old as long as both parties consent to the relationship and it is legal in their jurisdiction. However, laws regarding age of consent and statutory rape vary by state and country, so it is important to check local laws before pursuing any kind of sexual relationship. It is also important for both parties to consider the potential power dynamics and differences in maturity levels between a 17-year-old and a 19-year-old.
