Chances are even if a man was to have the Female Titan, their appearance would still be female. The Titan would essentially override any gender expression its inheritor would otherwise have shown in Titan form. Do we actually know that the Founding Titan changes gender? I think the only time we've seen it possessed by a man is King Fritz in a vaguely drawn way, and Uri in a skeletal partial form where it didn't have any features to define it one way or another.

Also, the female titan. Wasn't it only named that by the Eldians inside the wall because it was the first female titan they'd ever seen? They have no idea whether it's always a female because they've only seen it with Annie. And they barely knew about titan shifters at all back then, they didn't even know it was possible to pass titans between people.
