Due to hormone problems I'm pretty sure I'm growing hair way more than most girls my age. I also don't bother to shave, as I don't like shaving.

I've noticed years ago I had a mustache, even when I was a little kid; I always wondered why I had one but no one else my age did. It's gotten longer recently though.. It's not a big, fluffy male one but it's still facial hair; you can feel the fuzz. I'm gaining it under my lip, and sideburns too. I think I may be growing hair on the cheeks, but I hate how that grows so I cut any hair that comes out. 

It seems that a lot of boys my age have facial hair. People don't expect a girl to have that much facial hair I guess, if any. I guess I'm going through the "awkward" age though. It's too short to cut but it's still very noticeable.

Anyone else have any experience with this whatsoever?

No. If it's not like normal beard hair it doesn't help. I would shave it.

I think it depends on how old you look.  If you look like you could be thirteen, then I doubt it's a problem because people could assume that you're  just getting facial hair.  If you look much older, than it will hinder you from being read as male because men have full beards and some woman have facial hair.  Congrats on the hair.

Like Alex said, depends on your age. But even if you're younger, I'd stay, shave it. The sideburn-fluff that ladies have doesn't grow like that on guys I believe. And I actually think it's same with the mustache, even for a guy that just started growing facial hair, the look is very different. Better make everybody think you've got a bit more, 'cause you're clean shaven from chin to ears than 'female-fluff' so to speak.

Edit:
Even if it's extra female-fluff. My boyfriend's body (still pre-T) has higher T-levels than an average woman, also meaning more facial hair and a bit thicker here and there, but he needs to shave it as well 'cause it's still too feminine.
