Different is harder, but probably because 7/10ths of the stuff I read has a male protag rather than a female one. And I have little to no practice writing a female mc.Which is more difficult (subjective): narrating a protagonist according to the author's gender or narrating a protagonist different from the author's gender?
Same here, I got tired correcting my readers so I just let it be.As someone who’s always being mistaken for a man online, I think I can write a convincing male MC voice.
I would say "skill issue", but I will add because I try to be fair and balanced... "experience issue".It depends on what you're trying to do - I've attempted both, and, honestly, each has its challenges (even more interesting is having a first person narrator who was your gender but now is not and is trying to come to grips with this).
In general, its easiest to write what you know, and that, in at least 9 cases out of ten is the same gender as the author - but this is not always the case, depending on the story (and, possibly, if the author has gender issues of their own already).
