Rule about 18 year olds and minors dating
Also, my answer only discusses law in the United States.
It is legal for an adult to engage in social activities in public with a minor, such as eating at a restaurant or watching a movie - both of these activities are commonly associated with “dating”.
Other states imply a different method which, like the federal statute, takes into account the relative ages of both people.
In these states, such as Texas, the age of consent is determined by age differentials between the two persons and limited by a minimum age.
Luckily, CMB has a great report feature so if there's anyone making you feel uncomfortable, you can let the app know.I'm not sure that people think it is illegal to date a minor, but this can be cleared up with a better understanding of terminology.
