So I’m 15F and out as a lesbian to my parents and other sister (13), as well as various relatives and friends. My parents are extremely accepting and amazing about it and I really appreciate all they’ve done for me. 

My youngest sister is 9 years old and I’m talking with my parents about coming out to her in the next year or two. There’s no rush, there aren’t any real plans, but it’s on the radar for the distant-ish future. I may even postpone it until I have a serious girlfriend later in high school. 

But the thing is, she has no idea what any of that means. I’m not looking to teach her any labels or terms, I just think it’s appropriate for her to know, in simple phrasing, that some men and women can marry each other just like mom and dad do, and it’s the same kind of love. 

I’ve brought this up to my parents once or twice in pretty much the same wording I used above. They aren’t opposed to this idea, but seem to view it as something that would come further in the future. I think she should have this knowledge just as a reference point so that when I do come out to her in the future, she doesn’t find it weird and understands that I’m talking about romantic love, as in, someday I’ll grow up and marry a woman instead of a man, and we won’t just be _good friends_. 

I should probably add that my sister isn’t _immature_ per se, but isn’t the most mature in the world. I think she can handle it, though. She’s logical and empathetic.

So AITA? Do you think this is a reasonable request of my parents, or is it not urgent?
