I (cis male) feel more comfortable playing female characters in games and I have no idea why. It doesn't matter if I am crafting a unique character persona to play or whether I'm just going to play as some version of - if I roll a male character it just doesn't feel "right."
It's not about the size of the hitbox or wardrobe options, it's not about my avatars attractiveness or sex appeal. I'm not confused about my gender identity, at least, I don't think I am. I've been trying to muddle out why this is for years, yet I'm now middle aged and I still have no clue.
Recently I made it about 20 hours into Dragon's Dogma before switching from a 6' male fighter to a 7' female barbarian and immediately had more fun and felt more connected to the barbarian running around Gransys. It's like a discomfort/disconnect/discord I wasn't consciously feeling when playing a male, is gone when my character is female. I've repeated this pattern game after game, trying to play a male char and ultimately rerolling.
The best analogy I can come up with is music - when you hear a song you like you may not be able to explain why, your brain just enjoys it. When you listen to a song you don't like, your brain wants you just turn it off and listen to something else. It's mildly annoying as there are games with male-only content that I want to see but never make it that far, since i know I can be having more fun another way. Morrigan romance in Dragon Age, Panam content in Cyberpunk, etc...
Brains are weird.
