The age at which someone can legally date someone without being considered "underage" can vary depending on the country or state's laws. In many places, the age of consent is used to determine when an individual is legally able to engage in sexual activity with another person. However, it's important to note that "dating" and "sexual activity" are not always the same thing, and the laws may treat them differently.
In some jurisdictions, there might be a close-in-age exemption, often referred to as "Romeo and Juliet laws," which allow individuals who are close in age to have consensual sexual relationships without it being considered a criminal offense, even if one or both partners are below the age of consent.
It's essential to familiarize yourself with the laws specific to your location, as they can vary significantly. If you're unsure about the legal age of consent or other relevant laws in your area, it's best to consult with a legal professional or refer to reputable government sources for accurate information.
