(For those who are unaware, I'm talking about this trope.) In the fantasy series I'm currently working on, there's really only one aspect of the setting that I'm a bit wary of. The average life expectancy is 85-90 (as opposed to the current real world average of approx. 95-100) and the 'landmark' ages of the cultures are also adjusted for this. So, for example, marrying age in my world is around 14-15 in most places and about 2/3 of the countries in my world have a society where marrying for position or advantage is common so it's not at all unheard of for a 15 year old girl to be marrying a man or woman ten years older than her, or for a 15 year old boy to do the same. It's perfectly normal in-universe... I'm just a bit leery of how well an audience would take it. I have several characters who readers would probably consider to be young that are in relationships, some of them non-heterosexual. I'm aware that I'm probably going to have to be careful about how they're written and it's not as if I'm going to be going into, y'know, graphic detail, but I'd also rather not have to be coy about the fact that these couples are, well, couples. Any tips on how to manage that sort of balance?
