Premature ejaculation is defined as ejaculation occurring shortly after penetration or minimal penile stimulation. It can be distressing for men who feel they have little control over ejaculation. While most men wish they could last longer during sex, the average time to ejaculation is 4-8 minutes. Premature ejaculation is common, with surveys finding around 30% of men across age groups reporting climaxing too quickly at least sometimes.
