I don't understand how people are unable to roleplay certain genders, because I feel that it's not the physical aspects of a character - such as sex - that make them who and how they are, it's their mindset.
I am comfortable with playing all genders. I never have a balanced amount of genders, but I do have a lot of females and nonbinary characters at the moment. I also have a couple transgender characters and very little males. While I do try to balance it out, it never happens lmao.
