Duration of sexual intercourse related to satisfaction: survey of Japanese married couples.

Abstract

Inappropriate intromission time causes sexual problems for couples, and therefore it is important for the couple to set treatment targets. We investigated appropriate intromission times by conducting a questionnaire survey of the interval from initiation of insertion to just before ejaculation in Japanese married couples. A questionnaire survey of 300 married couples was conducted by mail. The estimated mean intromission times were 14.5 min (median: 10 min) for male subjects and 13.6 min (median: 10 min) for female subjects. The mean desired intromission time for female subjects was 15.7 min (median: 15 min). Regarding the difference between the actual and desired intromission times, the desired time was longer, the same, and shorter for 43.0%, 38.7%, and 18.3% of all the female subjects. It seems that female subjects may consider a wide variety of intravaginal insertion times to be desirable. Accordingly, married couples need to improve communication regarding the desired duration of intromission and other related issues.
