But why is it a problem that they’re a minor? A 17 year old and 18 year old (or 16-18) don’t have stark contrast in life experiences, have near-identical cognitive development, and don’t have any kind of power dynamic. I get that it can still just not feel right to you, as it did to me, but I don’t think it’s decidedly inappropriate for those relationships to happen.
I do find it easier to talk in terms of education levels though (assuming the people involved are typical ages for their grade level). If we’re saying the 16 year old is a high school sophomore and you’re a college freshman, then I would personally find that inappropriate, but I think a hs junior and college freshman isn’t unquestionably bad if you knew each other in high school (though I personally wouldn’t do it), and a hs senior and college freshman is completely normal.
