Lots of feminists don't agree with pornography no matter how sparkly, cuddly, fair trady, consenting and pollyannaish it is.
but lot's of feminist do agree with it too
Feminism is about challenging the status quo and the sexual hierarchy. It is about questioning sex roles and shining a light on the all pervasive domination/submission dynamic that places men as higher status than women.
and how does that have anything to do with women making erotica for other women to enjoy? 
Anyway, 'feminist porn' is a niche market drowning in the mass of violent hardcore misogynistic women humiliating abusive crap that makes up most porn - and this is the porn that most men consume.
ah so now you do acknowledge there is feminist porn! but is it really niche when you have masses of very popular erotic art sites like x-art, femjoy, joymii, met-art etc which are feminist approved and can be enjoyed by both men and women. There's nothing violent, misogynistic, humiliating, abusive about any of those sites. It's extreme porn which is a niche market. check out porn forums and search engines and you will see the most viewed threads/ popular searches are predominately softcore erotica.
