Confession: There was a time when I was thirteen years old in the midst of puberty, I rolled male protagonists primarily (KoTOR was the only RPG video game I had at the time), but occasionally I'd roll a female character because I thought they looked sexy (Some of those armors were quite... form fitting)... I always felt weird about it, certainly I'd never admit to playing a female character to any of my friends. let alone give that reason.
Eventually I did it less and played male characters almost exclusively by the time Mass Effect and DAO came around. That was around the time someone introduced me to D&D and the concept of roleplaying a character rather than projecting myself through the character.
That changed everything.
I started approaching RPGs in a completely new way. I experimented a lot in ME and DA with creating characters, male and female, looking to create experiences I would enjoy. No longer feeling bound to create avatars of myself, I became a lot more comfortable with creating and playing female characters (And no, I no longer stare at their bodies the whole time, though I do spend more time in the CC than I do the males. Making a pretty face is hard). My favorite versions of Shepard and Hawke have both been female (In both cases, because I prefer their voices to their male alternatives), and my favorite Inquisitor is female because I like the way the Solas romance plays out.
So... I guess what's most important to me is character creation, full stop. I don't care if they put a male, female, or androgynous armored form on the front, but they should get character creation out in the marketing.
