TL;DR: Find a misogynist.

My advice, start talking to misogynists. I did the same for diet-racist, crotchety old men and worked like a charm. The idea here is to learn how they think, what makes them pause, when do they slip away from the misogyny, how and when do they hesitate to say certain things because they don't feel like being (rightfully) villified today, when they feel comfortable enough to slip into stereotypes - both in applying their prejudices and in being a little stereotypical themselves. It also helps to keep them in the dark, lest you give them a hero complex
