There's an absurd gender dimorphism in most games where every guy is a mountain of muscles by default. I don't enjoy that body type - for myself, as a 5'5 dude, or even romantically - and women are usually on the softer, thinner side, so I tend to pick them at first.

If its a game where I can easily change genders, I'll flip around to my tastes, depending on which clothing looks better on whatnot. - Aliens:Fireteam Elite and Dragon Quest Builders 2 come to mind as examples that did that. Also games with intricate character creators, like Saint's Row (RIP) are welcome, but rare.

Eastern games tend to have softer men, so those tend to be exceptions. I recall picking male options in both Genshin and Path To Nowhere, and I usually enjoy the male leads in jRPGs.
