Though not quite the critics' favourite, the popularity of 'Fifty Shades of Grey' can't be denied - sales have already topped the 100 million mark. But is the book, which has a large following amongst the 40-plus crowd, responsible for their rising STI rates?

Dr Charlotte Jones, the chair of the British Medical Association’s GP committee spoke about how the novel encourages older people to explore their sexuality more. She said:

“When it comes to forgetting about safe sex we always think of the vulnerability of young people, but there’s the Fifty Shades of Grey effect where older people are being more explorative but not necessarily remembering to use a condom."

She also warned that STIs were a risk regardless of age and that precautions should be taken:

“Anyone, of any age, going into new relationships should be thinking about safe sex and particularly the role of condoms. People need to take care.”

The London Independent reports that between 2011 and 2012, STIs increased by 3% for those between 45 and 65, and 7% for those over 60.

So be smart, stay safe, and keep away from any predatory financiers!
