More than a third of women in the UK are not interested in having sex, a study has found.
Researchers conducted a survey of 12,000 Britons, asking them about their libido and attitudes towards sex.
Some 34 per cent of women admitted to not wanting sex, while the same was true for just 15 per cent of men.
Women also revealed they struggle to get aroused, had trouble having orgasms and found it difficult to enjoy sex.

Most people grouped into a 'low interest' category (80 per cent) were married or living with their partner, the study showed.
Sara Collins found her sex drive dwindling after her first baby. By the time a second arrived she and her then-husband Graham were sleeping in separate rooms.
They ended up splitting last year as a result and she says she is ‘no longer interested’ in making love.
‘When we were together I thought my husband was fine with our no-sex marriage,’ she added. ‘Turns out that he wasn’t.
‘It seems you’re supposed to want sex like you’re 17 all the time. But as I got past 45 it just wasn’t something that bothered me.’
Miss Collins, 50, a receptionist from Lancing, West Sussex, said: ‘Before we had children we would make love three or four times a week. But by the time I had our third child I was 39 and physically repulsed by my body.
'There was nothing I could do to shift the excess pounds. By the time I’d accepted it, I was in my late 40s and experiencing the perimenopause. I had hot flushes, was irritable and I couldn’t bear my husband near me.’
Researchers from the University of Glasgow analysed sex life questionnaires from a total of 12,132 people in the UK, between the ages of 16 and 74.
Each was asked about their experience of STIs, unwanted pregnancy, being coerced into sex, their physical enjoyment of sex and their attitudes towards it.
Overall, 47.5 per cent of women were deemed to have 'poor sexual health', which included emotional experiences as well as physical problems or illness.
In comparison, the rate was just 17 per cent among men. The research was published in the medical journal BMC Public Health.
Miss Collins said of the study: ‘I don’t think it’s surprising at all. I have one friend who hasn’t had sex in over ten years. However I think men will find these statistics quite shocking. Men put an awful lot more weight on a sexual relationship than women.
‘The most important thing for couples to do is communicate. If my husband and I had been a lot more open about how he was feeling I think we could have got some help or counselling.’
