Can a 13 year old date a 16 year old?

If the 13 yr old's parents allow it. But any sexual contact is illegal.

Agree, in fact both parents need to be aware of it and agree to it. And in addition to sex itself, there really can not no sexual type touching, often even though clothing with a 13 year old in most states.

You can legally but why would a 16 year old be interested in a 13 year old
