I like girls. I like how they look, I like the way they sound, I LOVE their fashion options. It isn't really any deeper than that. That said, I'll usually always play a male character in a Souls title, because [insert valid reason for inconsistency here.]
EDIT: I guess if I had to further expand on this, I'd say that female characters give me a way to explore options I don't have as a tall, bearded, broad, 'built' man. I've always loved cuteness, hyperfeminine fashion, "girly stuff", and so in addition to just really, really liking girls, video games allow me to explore the cute, feminine avenues I can't in the real world.
Also, as another commenter stated, I'd also just rather look at a girl's ass than a guy's for the entirety of a playthrough lmao
And you believe me, there is definitely a market for that lmao
Not here to tell you how to live your life, of course. But there are a non-zero number of people that would love to see that and not to make fun of you for it.
Shave your legs? If you want to dress in feminine clothes, just do it [if your country allows it].
I'd recommend against shaving your arms, though. Last time I tried that, it messed my sense of proprioception, turns out I'm used to the input of airflow over arm hairs to keep track of where they are, who'd know.

I often do this when I want the character to mesh with the build. If I'm playing a character with a great shield and giant hammer, I'll want a big beefy character that is often easier to create in game as a male body. And when I play a quick assassin, I often pick female. It's like the opposite of how anime weapons work.
FYI: as someone I think would like incongruent in girl mode, I went as Dr Frankenfurter (creation scene, was cold) for Halloween this year and went all out: full makeup, fishnets, shaved legs, 4" platform heels, etc. It was very fun and could be a good entry into what you might want to do. Also: you can always dress up at home just for yourself.
