It doesn't make a difference to me what gender the authors is, but I just realized that I feel the need to know what gender the author is. I assume the gender.
Sometimes I'll be reading a story and I realize I've been assuming the author is one gender, say male, and something in the storyline makes me think it's actually a female writing. So I check.
I'm not sure why I think like this. Heck, I'm not sure why I think a lot of the ways I think
Bet some of you might not be sure either...
(and I really do like a wide variety of genres, sometimes surprising myself by liking a genre I thought I wouldn't like at all, so that gives me access to a variety of authors of each gender)
