Panelist Chad Stefanyak suggests the 17-year-old may be immature and the 13-year-old mature for their ages, putting them on similar levels. If a 17-year-old is not as mature as his peers and all of a sudden a girl likes him, it could be very attractive, Stefanyak says. He may be invisible to girls his own age.

Is it wrong for a 17 to date 13?

No. It is not illegal for a 13 and 17 year old to date.
