How is premature ejaculation determined for men? What are the symptoms of premature ejaculation? Judging whether a male has premature ejaculation usually involves looking at the duration of intercourse, specifically the time from penetration to ejaculation. However, these are some unscientific ways to determine premature ejaculation. There are many causes of premature ejaculation, but they can be broadly categorized into psychological and physiological factors. In fact, whether a man has premature ejaculation depends on the situation. For example: whether he suffers from other male conditions [diabetes and premature ejaculation], or whether he has an overly long foreskin [premature ejaculation and long foreskin]. To answer how premature ejaculation is determined, we can say that for a healthy man, if ejaculation occurs within 2 minutes of penile insertion or just before insertion, it may indicate premature ejaculation.
