Gems are genderless humanoid alien energy beings with a wide range of body types and a tendancy to look and sound feminine by human standards. When they arrived on Earth 6000 years ago, everyone thought they were women, and they didn't argue because gems don't have intrinsic gender identities and they didn't have a cultural concept of gender back on the homeworld.

But, as Amethyst has demonstrated, gems who have picked up a cultural concept of gender from humans can and sometimes do deliberately assume gendered forms, including masculine forms such as the Purple Puma and the cop with the super-soaker.

If they eventually introduce an Earth gem who prefers masculine forms and masculine pronous, we'd pretty much have a trans character (well, as close to trans as a genderless polymorphic sentient space rock can get), and that kind of diversity doesn't get much representation in the mainstream media.

But, if they do eventually decide to introduce a full gem who prefers male pronouns, Yellow Diamond would probably be one of the worst possible choices, since it would create a plot hole (Jasper works for Yellow Diamond, and uses female pronouns for every gem including Steven because she doesn't understand human gender and thinks that Steven is Rose Quartz.), as well as making gems look like a society of magical space ladies, except for this one super-special dude who's pretty much their king.
