It would be nice to also acknowledge that grooming, exploitation isn’t always perpetrated by the adult/someone older. Kids/teenagers can groom, exploitation and take advantage of other minors and/or adults. Sometimes the older partner may be more innocent and niave and the younger person (minor) could have more knowledge or can be very manipulative.
The 16/12 proposal should acknowledge this.
I know someone who at around 11-14 claimed they were groomed, exploited and taken advantage by someone of very similar age.
