My opinion is like if you are dating if you're a guy in you're 18 and you're dating a girl who likes 16 or 17 that's OK but like anything below that is weird and if you're a girl who was like 18 and you're dating like a year below like 17 I think that's OK too and I think like if you're 18 either way and you're dating somebody that's like 23 or 22 I feel like 22 is the max for like oldest
