@Akayaofthemoon I always thought Ruby sounded pretty feminine, but Jasper's voice reminds me too much of my cousin with the weird gravely tone and everything who is 100% dude but with feminine-ish traits but is still clearly a dude and so I sort of saw Jasper that way they even share the long eyelashes and everything. XD I swear even her attitude reminds me of his when he was younger and maybe even a little bit today.
And it's okay, I know that's not the reason why you saw Ruby as such initially, otherwise you'd have to interpret either Pearl or Rose as male since though it's one-sided and the other may or may not be aware of it, it too is a thing. XD
