Nope, Titans don't have female/male versions from what I know.
Customization is:
Pilot skins
Primary weapon skins
Secondary skins
Titan skins
Titan nose art skins
Titan weapon skins
Banners
Patches
Banners and patches are locked away via challenges (kill X enemies, do, etc.) and some are "advocate gifts." Crazy amount of banners and patches for those who want to personalize stuff. I got a few animated ones already.
Not that concerned about weapons since they are giving out maps, modes and weapons for free.
Nine, with Angel City coming in December.
