Girl Ponies who you Think are Boys

[dragonfly]

Shady and Buttons are totally boys.
Possibly Bowtie. She may just be butch. I haven't decided yet.

[BrightSide]

Scootaloo! And Shady, definitely Shady.

I personally think DJ Pon-3 is genderqueer.

I always made G2 Silver Swirl into a boy and he would always marry Dainty Dove in the chappel xDDDD And then they would have Baby Swirly as a child~ I also matched other G2s, like Lady Cupcake (boy) with Lady Lightheart, Magic Motion Ivy (boy) with Pretty Parlor's Ivy (the long-haired) and some others I don't quite recall. All my G1s were girls because I never had many when I was a child

All the pony friends are boys in my eyes...

Tuneful! I didn't even realize she was a girl until I got her and saw she had eyeshadow on, lol.

Even then.. I still ignore it and she's still a boy to me xD

I second Wishawhirl. G3 Applejack too.

Oddly the only pony I ever thought was the opposite gender, wasn't technically a pony. He's a zebra!

I always thought Zig-Zag was a boy and found it incredibly odd reading his backcard later in life, where it said "she". I still think of him as a he.

My childhood Sparkle Sunspot was always a boy to me!    No idea why... but why not

Dibbles (? The yellow twin of the Nibbles/Dibbles set)

I am a lady. No but seriously...you are correct, it's Dibbles who's the yellow one. Her pink hair fades a lot, so I can definitely see why she'd be mistaken for a boy with white hair.

Scoops and Kingsly!

[ShannonInPonyland]

I always thought of G3 Applejack & Rainbow Dash to be boys when I was younger   
I picture G1 Bow Tie as a boy too sometimes. Ah, I know there's another pony too but I can't think of it

I didn't realize there was someone on here with that username!
Mine still has pink hair, but he just seems like a boy to me! It seems like in all the twin sets, I see one as a boy and one as a girl, too.

[Shimmer]

It's so interesting to see the ones being misstaken for boys alot, and I agree about the pony friends (Kingsley for example, lady lions don't have manes unless they have hormone issues)
I also always made the pony twins as one boy one girl it's more fun that way.

Most of our (my sisters and mine) were boys at some point: we had all our ponies marry my Pony Bride

She could just be the Adam Lambert of the pony world...
