I had hoped my first blog post for the New Statesman might be about my experience of sexism in the film industry (short version: it’s like 1950); that I think we should have a Good Sex instead of a Bad Sex literary award (why not celebrate decent, provocative writing?); or perhaps just a few lines on how underappreciated the naked male form is (and wanting this exhibition to come to the UK), but, instead, I am having to pen a piece about the way in which politicians are screwing us (no pun intended) over sex.

When it comes to sexual health, we seem to be seeing a subtle change in policy-makers’ decisions, with the vocal minority becoming more determined to influence the political mandate. Last year, I wrote this about Nadine Dorries MP, because her repeated attacks on abortion and sex education needed to be confronted. While it is nice to breathe a sigh of relief now, and know that her political objectives have been ridiculed (not least with her appearing on TV’s I’m A Celebrity), the fight for women’s rights over their own bodies still continues.

There is an undercurrent in UK politics, with, at its heart, an anti-sex, anti-women agenda. Bit by bit, the goal posts are being shifted and with each step pandering to the religious, anti-science, anti-choice ideologues, our rights, our ability to access healthcare, our freedom to make safe choices about our lives, get chipped away.

It’s incredible that we have a health minister, Jeremy Hunt, who wants the time limit for abortions to be halved, without any medical reason for doing so, and who fundamentally misunderstands that abortions are provided as healthcare for women – we shouldn’t need tragic cases like Savita Halappanavar to be reminded of this. But he sees this as a moral issue: he believes that personal opinions are the basis upon which to make medical decisions, not scientific facts. And he is in charge of women’s health. Great.

We also have a women’s minister and home secretary both pushing for four-week reductions. Besides ignoring their own parliamentary review (pdf) in 2006, which clearly states that there is no justifiable reason to decrease the 24-week limit because very, very, few foetuses are viable before then, these politicians press ahead with their ignorant opinions, arguing that “people’s views” should help form a pronouncement of women’s healthcare.

As well as the attacks on abortion rights, the coalition government is undermining sex and relationships education in schools and specialist services for young people due to their cuts in funding. If we don’t provide young people with comprehensive, age-appropriate sex and relationship education, which includes teaching about all forms of contraception, their sexual – and emotional – health will suffer. Brook, the sexual health charity for whom I am an ambassador, regularly asks young people what they want when it comes to learning about sex and relationships – and what they want is unbiased, balanced, knowledgeable sex education. Without this, they cannot make informed decisions about the sex and relationships they choose to have.

Simon Blake OBE, Brook’s Chief Executive, says:

“Most young people under the age of 16 are not having sex. Evidence shows that high quality sex and relationships education, provided by parents and at school, combined with access to free, confidential sexual health services helps delay the age young people first have sex and increases the likelihood they will use contraception when they do.”

If we don't fight against the encroaching attacks on access to abortion we will see a further deterioration of women's reproductive rights, and more women’s health will be at risk. And if we don't fight on behalf of young people and the sex education they are entitled to, then the impact on their lives, their relationships, and their sexual health, will be felt for generations to come.

In January, I'm running an event called Sex Appeal on behalf of Brook, to get people to openly challenge those who spread misinformation about sex, sexuality and sex education. We need to counter the spin that these anti-sex, anti-choice apologists are spreading – before it is too late.
