An erection occurs when the male penis is filled with blood. Also the muscles harden in the penis to make it hard with help of muscle linked to the anus. That's why a guy clenches up when he releases semen. Usually this process starts when the male thinks of something or sees or feels something that turns him on (gets him sexually aroused). That then causes the penis to fill up with blood, and harden, therefore creating an erection. Younger males sometimes just have erection 24/7 for no reason at all but apparently puberty.

Erections are not constant because the body has mechanisms that regulate blood flow to the penis. When you are not sexually aroused, blood flow to the penis is restricted by the contraction of blood vessels, preventing a continuous erection. Erections occur in response to sexual stimulation when these blood vessels relax, allowing increased blood flow to the penis.

Usually, a man experiences an orgasm soon after ejaculation. In fact, in male sexuality, orgasm is synonymous with ejaculation. After ejaculation the penile erection falls, and you must be sufficiently excited before you can experience another erection, leading to another ejaculation orgasm. It takes time. A minimum gap of 10 minutes is commonly observed between two erections. However, a gap of 30 minutes or more is advisable. This allows the stimulation to occur naturally, and so the erection that follows lasts longer. Remember, 'multiple orgasms' is basically a myth created by filmmakers. Stimulation, erection and ejaculation - they are all interrelated, and they occur 'naturally'. Artificial methods may lead to severe consequences. DURJOY GHOSH, BORAL, CALCUTTA
