tbh the only people I know personally (avatars are avatars in the end- may not reveal gender) on itch.io are women...
Also unfortunately your games may be seen as subpar just because you're not a man- it's hard to notice unless you submit the same game maybe with different stereotypical woman and man's name, and get different comments. Also, from my childhood I didn't know that it was odd or something for girls/women to take interest in games- we all played together on multiplayer games before the online stuff was popular. Then all of sudden I was introduced to a strange culture of women apparently not being interested in games...like what (even my grandma plays something...)
make what you like, play what you like, and remember, avatars are avatars (don't tell people all your info and be careful- this applies to everyone).
