Today's announcement by the Ministry of Justice of a new fund for male victims of rape and sexual violence is hugely significant.

The significance is not in the sum of money. While £500,000 is more than welcome, and will make a huge difference to the funded organisations and their clients, nobody would pretend it can do more than scrape at the scale of a problem which impacts an estimated 72,000 new adult victims every year and untold numbers of children. Nor does the significance lie in acknowledgement of the problem - charities have previously been funded for limited work with male victims, and in the light of historic sex abuse scandals in the Roman Catholic church and social service care homes, no one can plead ignorance as to the extent of horrors involved.

The significance is not even in the campaigning victory of charities like Survivors Manchester, who have fought persistently against the flagrant injustice of male victims being explicitly excluded from funds set up to provide care and support to victims of rape and abuse - although that achievement should not be overlooked. The historic significance of today's announcement is that it marks the first time that a British government of any stripe has ringfenced any quantity of victim support funding specifically to help men and boys. It may only be half a million quid, but it is a priceless milestone.

Although male victims make up a significant minority of cases of child sex abuse and of adult sexual, domestic and relationship violence, their specific needs and circumstances are often pushed so far to the margins of debate and policy that they all but disappear. In mainstream political and media narratives, the terms sexual violence and relationship violence are taken to be synonymous with the phrase 'violence against women and girls.'

This has consequences for male victims which go far beyond access to funding and resources. The voices and views of male victims are often excluded from debates about the investigation and prosecution of sexual crimes, despite considerable evidence to show there are specific and complex issues around men's and boys' willingness to report and testify. Debates around cultures of victim- blaming often focus exclusively on women's supposed behaviour or appearance, almost never on men's sexuality, despite extensive evidence that male victims, just like female victims, are commonly assumed to have been 'asking for it.'

While our society still has a long way to go before it treats the sexual abuse of women with the seriousness it requires, the equivalent journey for men has barely begun. Prison rape jokes in particular are almost ubiquitous. The ugly reality of that issue is stomach-churning rather than comic. One study drew upon interviews with ex-prisoners. The evidence was that while fewer prisoners are raped in British prisons than some people might imagine, those who are victimised are typically singled out for their physical and mental vulnerability and attacked repeatedly by multiple perpetrators. Detailed data on the extent of the problem in the UK remains elusive however because, shockingly, no one has ever commissioned or authorised the research to find out.

A different issue confronts the sizeable minority of male victims whose abusers are female. Despite clinical literature demonstrating that such victims face similar risks to other abuse survivors of post-traumatic symptoms, guilt, emotional and mental health risks and sexual dysfunction, victims often report feeling entirely isolated by a cultural denial of their existence. Boys who are abused by older women are told they should consider themselves lucky or grateful. While there is a large weight of evidence demonstrating that surprisingly large numbers of adult men can be victims of coercive or violent sexual abuse by women, their needs and situations are all but entirely ignored.

Perhaps the strongest argument for reserved funding for male victims is that if government won't help victims, nobody will. Charities working specifically with male victims tend to be desperately under-funded, the sad truth is that they are not considered the most sympathetic causes. Social psychologists have found that both genders, but especially men, are more likely to give to women in need than to men, which is generally attributed to socialised notions of chivalry. If ever you wanted an example of the feminist dictum that patriarchy hurts men too, it is right here.

Perhaps things are slowly changing. Similar points were made for many years about funding for research into male-specific cancers, but in recent years initiatives like Movember and Men United have brought glimmers of light to the gloom. Alongside the new funding, the Ministry of Justice have thrown their weight behind the survivors' charities social media campaign, #BreakTheSilence. Further support has come from the cast of Hollyoaks, which is currently running a sensitively-handled storyline of male rape. It is perhaps this gradual, public unlocking of the issue which, more than anything, can bring hope to survivors.
