At a certain point age becomes just a number. Certainly age can determine the expectation of maturity, aspirations, & life experience but to a youth the difference between a 60-YO human & a 200-YO elf isn't massive.I don't know, but for some reason, a 20-year-old woman marrying a 44-year-old man is a lot less palatable to me than a 20-year-old woman marrying a 200-year-old elf.
Same from a long-lived perspective, but that doesn't immediately make them a creep for having an interest in someone far younger than themself.
Only freaks & puritans obsess over age as a relationship factor rather than a mix of appearance & personality. (It's fine if you are either since you are yourself & not me.)
