actually yes there are some cultures, locations and religions that do have a rule around this. some even require a third party witness the event, some even prepare very young children for their "rite of passage" from childhood to adulthood rule through circumcision / mutilation type operations, and puberty party or ceremonies.

here in America we have no such rite of passage rule saying a person must lose their virginity by a certain age, though if you know any teens you would swear we had one lol the big deal around teens are who lost their virginity first and when and with who.

here in america we consider anyone who is 18 or older (sometimes 21 depending upon the state) an adult whether or not they have lost their virginity. some go their whole lives without losing their virginity and others have lost their virginity too young through abuse.

my suggestion is contact a medical doctor or mental health treatment provider in your own location and they will tell you if your location has a rite of passage rule that a person must have sex by a certain age. they will know the laws and rules about this kind of thing.
