Purpose Inappropriate intromission time causes sexual problems for couples, and therefore it is important for the couple to set treatment targets. Methods 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. Results 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. Conclusions 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.
