I used not to care much. Sometimes I do look at the sex of the Pokémon before deciding if I want to catch it, though.
Save for a few (like the butterflies or the rng 'mons from in-game events), I tend to go all-male when makin' a run~
Depends. Like primarina or gardevoir look female to me, so i prefer females of that species. But like granbull, klefki, or whatever gender neutral Pokémon can be male or female.
It depends on what I am doing I have done runs where I try and catch mostly female Pokémon depending on how I am playing the character in the game of course depending on the rarity of the Pokémon I may not keep with that. Then again I do some runs of a one the games and do not worry about the gender.
