Mine are all Super Cobras and a Hind D, thank you very much. Apaches aren't the only cool choppers out there, you know. For real though, if you wanted to get technical about it the only mounts that a known sex/gender could be assigned to would be the very first raptor, beetle, and skyscale you get. Because you only unlock them once for your account, any copies of those mounts your other characters use can be whatever you want. Of course, you can also headcanon the known ones however you want as well and nobody can stop you.
