Declining Sexual Activity and Desire in Women: Findings from Representative German Surveys 2005 and 2016.

We estimate (1) sexual activity and sexual desire in women living with and without a partner across the age range in Germany and (2) changes over 11 years. A representative survey of 1345 (response rate: 65%) women between 18 and 99 years from 2016 was compared to a survey of 1314 women age 18-91 from 2005 (response rate: 53%). Sexual activity was assessed as having been physically intimate with someone in the past year; frequency of sexual desire was rated for the past 4 weeks. In 2016, the great majority of women living with a partner were sexually active and indicated sexual desire until the age of 60, which decreased thereafter. Compared to 2005, fewer women cohabited with a partner. Across the age range, women living without a partner reported considerably less sexual activity and desire. The overall proportion of women reporting partnered sexual activity decreased from 67% to 62% in 2016, and absent sexual desire increased from 24% to 26%. Declines of sexual activity and desire affected mostly young and middle-aged women. The decline of sexual activity and desire seems to be due to a reduced proportion of women living with a partner. There was also a generation effect with younger and middle-aged women without a partner becoming less sexually active and experiencing less desire compared to the previous survey. While surveys were methodologically comparable, interpretations are limited by the absence of longitudinal data.
