Nearly half of millennial women aren't enjoying their sex lives, according to a new, first of its kind study by Public Health England.

The survey, titled 'What do women say? Reproductive health is a public issue', asked 7,000 women and found that 25- to 34-year-olds were much less satisfied with their sex lives than 55- to 64-year-olds, of whom a third were unsatisfied.

So there it is. The grim truth. Not content with banging their ways through a free uni education and banging in their houses which cost about £8 to buy, our parents' generation are still banging more happily than a lot of ours.

The study also showed that the importance of having an enjoyable sex life became more important over the course of respondents' lives. It was the most important reproductive health issue for around 16 percent of women between 25 and 34, but rose with every age group above that. Just under 40 percent of 55- to 64-year-olds said it was the most important reproductive health issue to them.

"Enjoying a fulfilling sex life is important for women's mental and emotional wellbeing," Dr Sue Mann, Public Health Consultant in Reproductive Health for Public Health England, told the BBC. "Our data show that sexual enjoyment is a key part of good reproductive health and that while many women are reporting sexual dysfunction, many are not seeking help."
