So, male authors, what do female authors do wrong when they are writing from a male point of view? And female authors, ditto: what do male authors get wrong when they are writing from the point of view of a female character?
Of course, not all authors will be guilty of these offences, but some of them will be accurate - and enlightening. I'm hoping to learn something from this so that I can fix it in any future stories, if I see myself in any forthcoming complaints.

So, here's mine. Sometimes the female character will be describing her own appearance inside her own head in great detail, as if she's going about her usual business while fixating on her luxuriant honey-blonde hair and arresting big breasts.
"Tiffani woke up and stretched lazily, wiggling her perfectly shaped smooth boobs at the ceiling, enjoying their heavy DD-cupped weight and bounciness. She would enjoy a cup of cocoa for breakfast today, she thought as she flipped her waist-length red hair behind her creamy 22-year-old shoulders, and stood up, feeling her fleshy butt cheeks bouncing up and down. I love how awesome my butt looks, she giggled boobily to herself as she took her gigantic boobs and porn-star-grade butt to the bathroom to pee."
As a woman, I do like my own boobs, but I have never once had a thought like that.

So what do we authors - men and women - do wrong?
