There have been several articles in the news, lately (Thanks to Penis-Beaker, no doubt) about Mumsnet regarding members discussing sex and suggesting that it is a negative thing. Why the outrage?! There are hundreds (thousands? millions?) of sites dedicated to Porn, promoting the more misogynistic acts of sex, rating women on their performance in the sex industry. There is porn on the shelf in corner shops and lads mags in supermarkets.
As far as I can tell men of all ages, job descriptions and parental status are allowed to indulge in their base instincts but mum's are not. Bit of a Madonna-Whore complex by the media in general. It's ok to like sex if you are pretty and discussing it in the realm of men, for men, and in a way that men like. But it's not ok for women to discuss sex in a forum mainly frequented by women. Especially one mostly used by mothers.
I just don't get it. There are constant jokes and criticisms about how all mothers lose their libido after children and yet when an opportunity arises to dispel this myth people don't like it. We should all go back to just discussing child-rearing and the many uses of baking soda 
So, men can divulge and indulge in deviant ideas but women shouldn't ask their friends if these things are normal...
One article said these things are private but their not really are they? We have sex aimed at us by the advertising industry and media in general but we're not allowed to discuss it? We are supposed to listen to what men and the media want - shave your armpits, wax your genitals, make them smell like flowers, have a skinny waist and massive boobs, make sure they're pushed up and in etc. without checking with other women if they think this is all normal.
The reason all this bugs me so much is because I grew up in this world and my DD is going to have to as well.
I grew up seeing lads mags (and the Sun) on coffee tables read my the fathers of my friends, my brother, all my boyfriends and their friends. Objectification of women was normalised and I suffered for it.
The thing is I look like I turned out ok and I'm sure I did for the most part so people will say "ah well, it didn't do you any harm" but I think it did.
