Statistics show that around 50-65% of women have faked it at some point. We’re almost certain you can probably think of a time when you’ve done the same – or at least a time when a friend of yours has admitted to doing so – proving just how often women miss out on having the great time in bed that they deserve.

But why is this? Well, of course there are many reasons (the porn industry, the male ego and the fear instilled in women to never seem wanton, to name a few), but Campbell reckons something that could really help us reach climax is, simply, wanking more.

Campbell explains: “For boys, wanking is a normal part of life that they’re proud to talk about with anyone they meet. For girls, that coming of age moment isn’t a wank, it’s a period.

“Girls aren’t taught about masturbation as being a healthy, normal part of their sexual development. Girls are taught that wanking is for boys, and this is why we have to wank.”

Why women need to wank more, according to Grace Campbell
