I should point out that I in no way meant to make it sound like these attitudes were only the attitudes of men. They're not. Nor are they only harmful for women, they're incredibly damaging to men. When it comes to belittling women who do seek out casual sex, women can be just as vile - as any teenage victim of bullying will tell you - and women's magazines and the like further perpetuate - at least in my opinion - that women and sex are somehow these two newly-introduced concepts that were once thought incompatible.
We may not like to hold these attitudes personally, and personally, I don't know anyone who really has these attitudes (at least not openly). But there's also the "slut" vs "player" problem - again, this is damaging to both genders, because it demonises females who enjoy rumpy-pumpy, but also further perpetuates this line of thinking that a man is untrustworthy in a relationship unless he's 'tied down', or that it's somehow shameful for a man to be a virgin after a certain age.
It's like this absurd ridiculous vicious circle. The attitudes cease to be as prevalent, but the 'aftershocks' of such attitudes continue - even if it's all self-imposed pressure to be a certain way because of an "expectation" which has stopped being there - I suppose that's why being vocal about it is quite important. It's starting to unravel - I agree with you, Si, things are moving fast - but these attitudes do exist, and sometimes only become apparent in an unexpected moment. I remember a female friend telling me that she once took a guy home from a date, and he couldn't believe his luck - pulled a girl who goes 'all the way' on the first date. Marvellous. Anyway, they got down to it, had a great time, and it came to the inevitable post-sex talk, and the talk of previous partners. Now, in all honesty, this girl has had her fair share of men. Doesn't boast or brag, but if you ask her, she'll be honest and upfront about it. And so had he.
Now on the surface, he was a lovely, genuine, charismatic guy. But he couldn't handle the fact that she'd had so many partners - whilst being completely oblivious to the fact that anything he could accuse her of, or anything he felt, could be applied just as equally in reverse. Now, I'm not saying this was due to some huge, misogynistic urge from deep inside of his psyche, probably nothing more than him feeling a little insecure, what with all the potential 'rivals' for bedroom performance scores. But there's a double-standard there, and there's nothing wrong with highlighting that, because it's quite pertinent.
Other double standards, like the expectation of women to be naturally wonderful mothers because - well, women are women, right? - isn't just a kick in the arse for every woman that doesn't want to be a mother, or can't be a naturally great mother - but it's also a kick in the arse for every man who is, or wants to, stay at home with his kids, to every man who has had to go and take a job far away from his family in order to 'provide' in his role as father, for every man who has unfairly lost access to his kids.
There's a bit of an issue here in that far too often gender-topics then become gender-wars: men vs women, and it becomes some ridiculous 'Suffering Top Trumps' where both sides try and make out they're the most hard done by. But the reality is, it's a pathetic human problem that we'd all benefit from sorting. That's why I find myself annoyed by deliberately divisive images, pictures, etc with nothing to say about it. It's fine to point out the double-standards, as long as you can point out what the double-standards are, why perhaps they're there, and what can be done - again, this is on both sides. Otherwise, it's a case of 'what's your fucking point?' and you just make yourself look like a complete and utter cunt.
