Lion has a mane which indicates him being male, Lion won't have a gem on his stomach because Steven has Rose's gem. The fact that Steven was able to enter Lion's mane isn't proof that Lion is Rose as we don't know if anyone is incapable of entering his mane, and Rose could've used Lion's dimension as a way of keeping things precious to her safe as she (presumably) trusted Lion.
