Lion could easily be either gender, I agree. Considering the appearence of Lion, it is actually rather likely that Lion is male. A female Lion actually doesn't generally have a mane and is called a Lioness, so it seems rather likely that Lion is male.

If this theory is correct and Lion is actually some form of Rose, then it would imply that gems are genderless but take female humanoid forms most often. For instance, Amethyst and Garnet have morphed into Steven a fair amount of times, so it could be implied that they essentially changed gender (although one would argue that they never changed gender and merely appearance) although in actual fact it is very likely they never really had a gender to start off with. Seeing as Rose Quartz had to transform a womb in order to give birth to Steven, it seems very likely that gems do not actually have the reproductive organs to even identify as female.
