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.
目的
插入时间不当会给夫妻带来性问题，因此夫妻设定治疗目标很重要。
方法
我们通过对日本已婚夫妇从插入开始到射精前的间隔时间进行问卷调查，来研究合适的插入时间。通过邮件对300对已婚夫妇进行了问卷调查。
结果
男性受试者的估计平均插入时间为14.5分钟（中位数：10分钟），女性受试者为13.6分钟（中位数：10分钟）。女性受试者期望的平均插入时间为15.7分钟（中位数：15分钟）。关于实际插入时间与期望插入时间的差异，在所有女性受试者中，期望时间更长、相同和更短的比例分别为43.0%、38.7%和18.3%。
结论
女性受试者似乎可能认为多种阴道内插入时间都是理想的。因此，已婚夫妇需要改善关于期望插入持续时间及其他相关问题的沟通。
