Researchers at Southampton University in the UK believe that women’s interest in sex tends to die down after a year of living with the same partner, reports IOL. The study is the largest one of sexual habits in the UK.

The findings, which were published in the third National Survey of Sexual Attitudes and Lifestyles, found that men and women view sex differently. Men are reported to still be very much into sex a year into the relationship.

The researchers interviewed 6 669 women and 4 839 men aged 16-74 who had one sexual partner in the past year. Some 34% of the women and 15% of the men said they lacked interest in sex – and were distressed by this.

Those who lacked interest are encouraged to communicate openly with their partner, especially when it comes to sex.

Lead researcher Professor Cynthia Graham, from the Centre for Sexual Health Research, said: “Our findings show us the importance of the relational context in understanding low sexual interest in both men and women.

“For women in particular, the quality and length of relationship and communication with their partners are important in their experience of sexual interest.

“It highlights the need to assess and, if necessary, treat sexual interest problems in a holistic and relationship, as well as gender-specific, way.”

In addition, researchers found that as women get older, their interest in sex declines. However, men are said to stay interested – until their 70s.

Co-author Dr Kirstin Mitchell of the University of Glasgow said: “The findings on the strong association between open sexual communication and a reduced likelihood of sexual interest problems emphasise the importance of providing a broad sexual and relationships education, rather than limiting attention only to adverse consequences of sex and how to prevent them.”
