I have my wife read selected chapters here and there as I write the first draft. It's always to see if I get the female pov and verbal cadence correct. When she's done I ask her, what was the female character thinking / feeling? Often my male character doesn't know all the motives/meaning etc behind the female character's words and actions (he's just observing).

IMO female authors who write a male MC almost always get it wrong, or don't go deep enough to see motivations etc. My wife tells me that male authors that write female character are just as bad.
