Your opinion of this new popular dating trend in high schools?

I read that in many schools recently there's been a growing trend of 16/17 year old girls getting a younger 13/14 year old boyfriend instead of going after old guys, because the attraction for the older girl is she gets to take the lead role in the relationship and have the chance to "teach" the younger boy how to kiss, what to say on a date, how to treat women, how to respect them etc.
