The Male Orgasm: Steps to Ejaculation
The steps that lead a man to successful orgasm include:
Arousal The man perceives something or someone that prompts sexual interest. That perception prompts the brain to send a signal down the spinal cord to the sex organs, causing an erection. The penis becomes erect when blood fills spongy tissue inside its shaft, brought by arteries that have expanded to allow blood to race in at up to 50 times its normal speed. The veins in the penis that normally drain blood out squeeze shut so that more blood remains inside, producing a firm erection. The scrotum pulls toward the body, and muscles throughout the body increase in tension.
Plateau The male body prepares for orgasm in this phase, which can last from 30 seconds to 2 minutes. Muscle tension increases even more and involuntary body movements, particularly in the pelvis, begin to take over. The man's heart rate increases to between 150 and 175 beats per minute, says Ingber. A clear fluid may begin to flow from the urethra. This pre-ejaculatory fluid is meant to change the pH balance of the urethra, to improve the chances of sperm survival.
Orgasm The orgasm itself occurs in two phases, emission and ejaculation. In emission, the man reaches ejaculatory inevitability, the "point of no return." Semen is deposited near the top of the urethra, ready for ejaculation. Ejaculation occurs in a series of rapid-fire contractions of the penile muscles and around the base of the anus. Involuntary pelvic thrusting may also occur. The nerves causing the muscle contractions send messages of pleasure to the man's brain.
Resolution and refraction After ejaculation, the penis begins to lose its erection. About half of the erection is lost immediately, and the rest fades soon after. Muscle tension fades, and the man may feel relaxed or drowsy, according to Ingber. Men usually must undergo a refractory period, or recovery phase, during which they cannot achieve another erection. This period is variable in men, says Ingber. In an 18-year-old, this is typically less than 15 minutes. In elderly men, it can be up to 10 to 20 hours. The average refractory period is about half an hour. Men differ from women in that men usually are satiated after one orgasm. Women can experience more than one orgasm with no loss of sexual arousal, and do not have to undergo a refractory period.

Dopamine. This is one of the “happiness hormones” that’s related to your brain’s reward system.
Dopamine is a type of neurotransmitter. Your body makes it, and your nervous system uses it to send messages between nerve cells. That's why it's sometimes called a chemical messenger.
Dopamine plays a role in how we feel pleasure. It's a big part of our unique human ability to think and plan.

Endorphins. The body’s natural pain reliever, endorphins also have de-stressing and mood-boosting effects.
Endorphins are chemicals produced by the body to relieve stress and pain. They work similarly to a class of d**gs called opioids. Opioids relieve pain and can produce a feeling of euphoria. They are sometimes prescribed for short-term use after surgery or for pain-relief.
Endorphin rush." Sex, exercise, even hot peppers -- all sorts of things are credited for these euphoric highs. So what are endorphins, and are they really responsible for our feelings of excitement or satisfaction?
Endorphins may also be responsible for heightened states of rage or anxiety. If your endorphins overdo their job or the hypothalamus misreads the endorphin cue, you could be flooded with "fight-or-flight" hormones at the slightest hint of trouble or worry.
Endorphins affect us like codeine or morphine do, but without the addiction.

Oxytocin. This hormone is often called the love hormone and is associated with social bonding.
========================================================================================
Testosterone. This hormone is released during sex to improve stamina and arousal.
It’s also released when you have sexual fantasies,
Many people believe that masturbation affects a man's testosterone levels, but this is not necessarily true. Masturbation does not seem to have any long-lasting effects on testosterone levels. However, masturbation may have short-term effects on the levels of this hormone.

Prolactin. A hormone that plays an important role in lactation, prolactin also influences your mood and immune system.
