Just to bring it back on topic I remember reading in The Animators survival kit (essential if anyone wants to learn animation) there is a part about female/gay walks.

^page 110 on scribd 104 in the actual book

A masculine walk keeps feet paths almost parallel, females tend to put their feet more one in front of the other and keep the ankles really close. This means that feminine walks don't bob up and down as much.

If anyone wants to get into Animation this is the Bible of Animation, even if you don't it's a pretty interesting book.
