I've spent the day veiwing various websites through regender.com . Basically it switches all masculine words to feminine and v.v. It's really interesting to read for example, bbc news and see how out of place some of the headlines look if you swap gender. (Also reading this site, or a feminist site through the filter is very interesting. You notice gender where you don't usually see it, because it gets mentioned differently)
Phrases like "We have three children already, I want another baby, but my wife isn't interested", jumpt out at me because somewhere, unconciously, I expect people to act the way society says their gender role should. Slowly, I'm trying to drag it to the surface and notice all the assumptions I have about men and women that simply do not hold up.
Also, if you want a good laugh try it on a dating tips site. The advice given is simply hilarious why the genders are swapped round

I found a lovely one suggesting if a women wants to get a guy, what she should do is go to a laundrette and play dumb - men apparently love "helpless" women who don't know how to do their own laundrey and need to be shown how to get stains out of clothes.
