I haven't met too many 16 year-olds that thought they weren't mature for their age, in their humble opinions.

One consideration: If a teen is in an illegal relationship with an older man because they know they are mature enough for it, they are missing the point that responsible consideration of risks and consequences - both to oneself and maybe especially to others - is a key characteristic of maturity, so they've already failed that test.
