The basic data about sexual life is very important, however, we do not have much of the basic survey data about female sexual activities.
Methods: The internet based survey was done in women in their 20s to 50s. Those who were having sexual intercourse regularly at least once a month in the past 6 months were requested to answer questions about sexual life, perceptions, and clinical symptoms. This is a 10 year follow-up study from 2004.
Results: 516 women replied, of whom 148 were single and 368 were married. The mean frequency of intercourse per month was 3.46 ± 2.56. The estimated average coital frequency in 2014 (3.80 ± 2.63) had decreased from that reported in 2004 (5.34 ± 3.84). It had decreased especially in the study group of 20s and 30s. Using multivariate analysis, the risk factors of reduced sexual intercourse frequency were found to be single status, less value on sexual activity, and less conversation about sexual activity between couples and aging. 84.5% of women were using contraception and 63.8% used ineffective contraceptive methods like extra-vaginal ejaculation and menstrual cycle. This trend was similar to that seen from the 2004 study. Most Korean women had positive attitudes towards sex (3.2 ± 0.6 points out of 5) and considered it to be important (3.3 ± 0.7 out of 5). However, women in 20s and 30s had less positive attitudes towards sex than in the past decade.
Conclusions: Compared with the past decade, decreased mean coital frequency of Korean women was prominent especially in the women of 20s and 30s, and the risk factors were aging, single status, less value on sexual activity, and less conversation about sexual activity between couples. The attitudes towards sex life were less positive in the younger age groups than in the past decade. Still many women used unreliable methods of contraception. More intensive education about contraception is needed for the younger generation.
