Mistake 1. Turn away from her and fall asleep immediately after orgasm.

You may think it's "natural". After all, didn't you have a long day at work, and weren't you the one who just worked hard to get her to orgasm BEFORE you? But, for your woman, the ability to fall asleep immediately after means only one thing - insensitivity. In fact, women think: “he only needs this from me, he got what he wanted, and now he is sleeping!” What do you do when you really really want to sleep? Come close to her and hug her. You can also stroke her hair (generally the best way out, because it will make HER want to sleep.)
