Physical, chemical and emotional/psychological factors cause premature ejaculation. Physical and chemical problems include: An underlying erectile dysfunction diagnosis. A hormonal problem with oxytocin levels, which has a role in sexual function in men.
How does ejaculation occur? Sexual stimulation and friction provide the impulses that are delivered to the spinal cord and into the brain. Ejaculation is a reflex action controlled by the central nervous system. It is triggered when the sexual act reaches a critical level of excitement.
Delayed ejaculation can result from medications, certain chronic health conditions and surgeries. Or it might be caused by substance misuse or a mental health concern, such as depression, anxiety or stress. In many cases, it is due to a combination of physical and psychological concerns.
Occasionally losing control over ejaculation is normal. Premature ejaculation is only a problem if it happens frequently. Most men occasionally reach orgasm sooner than they'd like. For example, it is common for a man to ejaculate quickly the first time he has sex.
The answer to the question, “what age does a man stop getting hard?” is simple: it doesn't exist. Some men in their 90s can still get erections without any trouble, while many men in their 20s struggle with erectile dysfunction.
During sexual intercourse, most men ejaculate between 5-10 minutes and research has shown the average time to ejaculate after penetration is 5 1/2 minutes. Usually, ejaculation less than 1 to 1 1/2 minutes after penetration is regarded as premature ejaculation.
It is completely healthy to ejaculate more or less than three times a week! The average ejaculation frequency for men ranges from two to seven times a week, which is a pretty wide gap. So it's clear that there's no right or wrong answer, nor are there any significant health risks associated with ejaculation frequency.
