The duration of sexual intercourse for men generally falls within the normal range of 3-10 minutes. The specific time is influenced by factors such as psychological state, physical fatigue, and partner coordination. The International Academy of Sexual Medicine defines the intravaginal ejaculation latency period as the time from penetration to ejaculation, and most studies show that the average duration for healthy men is 3-10 minutes. This range encompasses data from men of different ethnic and cultural backgrounds. A duration shorter than 1 minute may indicate premature ejaculation, while a duration exceeding 30 minutes may indicate delayed ejaculation. Time judgment should be combined with mutual satisfaction, as evaluating solely based on minutes is not comprehensive. Some men can moderately prolong the duration through behavioral training, but deliberately pursuing an excessively long duration may lead to sexual pain or decreased pleasure. A regular sexual frequency helps maintain stable performance, and it is recommended to maintain 2-3 times per week.
