I spent a fair bit of time yesterday writing up a large article on the history of porn for women.
The article looks at the origins of the male centerfold in the 70s and tracks the development of women's porn through to the present.
It's not a huge history, admittedly, but it's still quite expansive given that many people still don't believe that "porn for women" is a legitimate idea.
We've come a long way, baby.
