I always make a male and female character and give them the same name from my other games if possible (I gave them personality/backstories in my head, dont ask). And sometimes I make multiple characters from different classes, species, races, skin colors etc. and if I feel creative, their back story/bio. Helps if one is a creative person that likes to write stories.
In a lot of cases (not the people here) it's because they like having a woman they can oggle from every angle and exercise complete control over. See Shaun's most recent video; if it's enough to be a core conceit of reasonably popular video games, it's enough to motivate g*mers in other games that treat their female characters just a misogynistically.
Plenty of people have other reasons, of course.
Look, mithra has the highest Dex stat and I want the biggest sneak attacks possible. I'm not one of those gooners who wants to lock style in the wedding gear, my mithra stays tastefully purple with the bastokian aketon and those rad goldsmithing glasses
I support our rogues, they work hard to circumvent the combat mechanics
