lol Well, an RP is an RP... one things people seem to forget is that kids can start being interested in sex at a very young age; it's normal for, say, a 15 year old to start experimenting. It isn't KOSHER and you can't try to publish anything like that without being arrested (unless you're the author of Clan of the Cave Bear... for some reason I wanna say Ayla was underage) but personally I love writing teens and young folks and yeah sexuality can and often is a part of their lives, so... now 11 years old is a bit young, so I hear you 
I'm struggling with the ages of my characters in the story I'm working on (the one I sent you a summary for). Like you I think I naturally gravitate towards writing younger characters, but then that becomes a problem when I try to include romance. My main character went from 19 to 17, but then I realized he may "get busy" with his spouse at some point, so I forced myself to make him turn 18 during the course of the novel. But then I started to feel concerned about the age discrepancy between him and his future husband, so I dropped future husband's age from 25 to 23. And after a point it's like you sit back and ask yourself, Who even ARE these characters anymore??

Oh and to my last post I meant to add a picture of Fenris that someone created in DAI (obviously using mods, but still):

Which makes me think FB3 is just really really amazing and capable of creating gorgeous people, BioWare's inability to create hair notwithstanding.
Hmm actually one of the narrative RP was with a girl who agrees to let me try the real characterization of the boy in Hogwarts AU. So I keep him really in character with translated backstory etc and it's not a very happy one. And it's based on a real life little boy with similar problem I get to observe, all the ticks etc2 although tbh it's just a freakingly heartbreaking one. I never see a child that nervous and timid to that point... He is cute as hell but the way his family treat him is just... I never see a child looking that vulnerable and nervous and quiet as hell. When you see that kind of thing it's rather hard to... ignore. I just keep seeing him in my head.
This is from the clip (I see him like this actually, slightly darker hair)
It's just feel so FREAKING wrong to...
About RP Idk how others do it? The 3 people I do it with do the RP for the reason of wanting to Flesh characters for some reasons so... we do it narrative? Like we do it in prose form that we put in AO3. It's really not just *smut smut smut/fluff fluff fluff * like somehow most people do? (Idk how to do that?) Those RP I do have game-over point and end up freaking dark O.o
Guess that ages are less relevant once you past the certain age? I mean in the case of immortal People, 1000 years of difference is probably small... For someone at 35, dating someone at 40 is small... But a 16 years old dating 11 years old? O.o So why not age everyone up? Just an idea :3
And sorry for the OT XD
