There was a post earlier on asking whether the age of a person matters in a relationship and someone replied that a couple in their 20s, age difference is insignificant but high schoolers and college students shouldn't date? Assuming there is no legal barrier, do you think it should be fine for a, let's say, 17 year old (just below the legal age in most countries) to date a 20 year old or a 21 year old? What do you guys think?
