I wouldn't schedule things. That just doesn't work. Mega is right that calling you a bad lover is her counter attack defense. Call her on it: ask her to be specific, what can you do to improve, when can you try these things on her.
Then again, if she is really good, she'll shut you up by telling you your penis is too small .
