Healers and casters have generally always been in the direction of being robes, as is depicted widely across many genres and not exclusive. People have asked for many things, whether between ARR, HW, or SB that's beyond a 5 year disparity at this point. I'm not sure what my glamour has anything to do with this, I have several glamours, both of which are mixed between genders. Furthermore, I have had male characters for just about as long as I have had feminine. One of my alts is a male Viera, even. -- I misundestood this one, apologies - But I'm sorry, they still have the armor sets from the Knights' Round. This is just playing whataboutisms. So why don't you try and pull a different leap in logic with this. Equally your character has a hairstyle which I would deem to be of a feminine nature, therefore you must have some leaning preference towards feminine characteristics. The Warrior of Light has been a staple posterboy for the entirety of the expansion.
But whilst we're on meaningful statistics which have as about as much influence of what is incorporated as much as Yoshida's own personal preference. Your own personal feelings aside the game has a pretty large and overwhelming feminine character-base. This has more influence than the leap in logic that Yoshida cares for feminine exclusively because he elected to roleplay as a feminine character. -- Oh hey look, still no female Hrothgar either.
