Long-term relationships may offer many psychological advantages but staying in a monogamous relationship for long may reduce a woman's sexual desire, a study says.
Following over 2,000 premenopausal Finnish women for seven years, the researchers found that those who had remained in the study period experienced the greatest decline in sexual drive.
The scientists used the Female Sexual Function Index -- a brief survey that quantifies particular areas of sexual functioning in women, like sexual arousal, orgasm, sexual satisfaction, and the existence of pain during intercourse -- to look at the development of female sexual desire over an interval of seven years, Medicalnewstoday.com reported.
Analyses were conducted separately for girls in distinct relationship constellations.
Of the functions analysed, the researchers found that the ability to orgasm of women stayed the most constant over the seven-year interval, while sexual satisfaction fluctuated broadly.
During the seven-year follow-up, the ability to have orgasm improved across all groups, with single women experiencing the largest advancement.
Women with a fresh partner experienced higher advancement in orgasmic skill compared to girls who had been over the whole span of observation in the same relationship.
