Researchers carrying out the survey interviewed 6,669 women and 4,839 men aged between 16 and 74 who reported having at least one sexual partner in the past year.
British women have a greater tendency than men to go off the boil after a year with the same partner, new research suggests. It is conducted by the University College London, the London School of Hygiene & Tropical Medicine and NatCen Social Research.

Poor physical and psychological well-being, poor correspondence and an absence of enthusiastic association amid sex were the primary reasons why men and women lost intrigue.
The researchers found that overall 15% of men and 34.2% of women reported lacking interest in sex for three months or more in the previous year.
Women who had recently masturbated reported a greater interest in sex compared with men who reported to be less interested in sex, the study said.
Open communication between partners increased interest in sex for both genders, the researchers found, especially among people in long-term relationships.
Men between the ages of 35 and 44 are likely to lose interest in sex according to a sexual attitudes survey, whereas women are likely to experience this much later in life.
Graham noted that for women, in particular, the length and quality of the relationship and communication with their partners "are important in their experience of sexual interest".
For some, it is a natural and normal place to be, but for others it causes pain and misery.
Although it didn't really effect men, having young children in the same household proved to be a particularly potent mojo-crusher for women.
However, couples who "always found it easy to talk about sex" were less likely to lose interest, as opposed to those who experienced sexual difficulties and lacked closeness in their relationships.
"This study extends our understanding of the factors associated with lack of interest in sex in men and women, the gender similarities and differences", the author's wrote in their conclusion, "and highlights the need to assess and - if necessary - treat sexual desire problems in a holistic and relationship, as well as gender-specific way".

"It is vital to look past against depressives", Prof Graham said.
