Testes
The testes lie outside the abdominal cavity of the male within the scrotum. They begin their development in the abdominal cavity but descent into the scrotal sacs during the last 2 months of fetal development. This is required for the production of sperm because internal body temperatures are too high to produce viable sperm.
In the body of an average male, there are two testicles located in a sac called the scrotum. On top of these organs is the epididymis, the "housing area" for sperm that has been produced.
Penis
The penis has a long shaft and enlarged tip called the glans penis. The penis is the copulatory organ of the males. When the male is sexually aroused, the penis becomes erect and ready for intercourse. Erection is achieved because blood sinuses within the erectile tissue of the penis become filled with blood.The arteries of the penis are dilated while the veins are passively compressed so that blood flows into the erectile tissue under pressure.
Sperm & seminal fluid
Main article: Spermatozoon
A mature sperm, or spermatozoan, has 3 distinct parts: a head, a mid-piece, and a tail. The tail is made up of microtubules that form cilia and flagella, and the mid-piece contains energy-producing mitochondria. The head contains 23 chromosomes within a nucleus. The tip of the nucleus is covered by a cap called the acrosome, which is believed to contain enzymes needed to breach the egg for fertilization. A normal human male usually produces several hundred million sperm per day. Sperm are continually produced throughout a male's reproductive life, though production decreases with age.
During ejaculation, sperm leaves the penis in a fluid called seminal fluid. This fluid is produced by 3 types of glands, the seminal vesicles, the prostate gland, and Cowper's glands. Each component of a seminal fluid has a particular function. Sperm are more viable in a basic solution, so seminal fluid has a slightly basic pH. Seminal fluid also acts as an energy source for the sperm, and contains chemicals that cause the uterus to contract.
Ejaculation
Main article: Ejaculation
As sexual stimulation becomes intense, sperm enter the urethra. Sperm and seminal fluid together are called semen. Once semen is in the urethra, rythmical muscle contractions cause it to be expelled from the penis in spurts. During ejaculation, the bladder is closed off so that no urine enters the urethra. The contractions that expel semen are also a part of male orgasms. There may be more than 400 million sperm in 3.5 milliliters of semen expelled during ejaculation. However, fertilization may still occur even if the sperm count is lower.
Following ejaculation and/or loss of sexual arousal, the penis returns to its normal flaccid state. After ejaculation, a male typically experiences a period of time, called the refractory period, during which stimulation doesn't result in an erection

The male reproductive system consists of :
1-2 testes which lie outside the body in a sac called scrotum
the 2 testes are responsible of producing sperms and male sex hormone [testosterone] .The scrotum keeps the temperature of the testes lower than the body to continue producing sperms.
The testes is composed of a large number of fine convoluted tubules called semeniferous tubules.
2-Vas deferns:it opens into the urinogenital duct.It transmits the sperms from the semeniferous tubules to the urinogenital duct.
3-Genital glands:cowper's gland-semenal vesicle-prostate gland
These glands are responsible for producing semenal fluid.
4-Penis:the male reproductive system ends by a common opening called urinogenital opening . The urethra extends in the penis.Sperms,semenal fluid and urine gets out the body through thr urinogenital opening.

The testicles (goolies) are very sensitive to heat, that's why they drop if they get hot. It's also extremely painful if you get kicked in the goolies. Then there's the prostrate gland, part of the male reproduction system. This is considered to be the male 'G spot' and is located inside the rectum, behind your goolies. Gentle massage of the prostrate can make a guy climax like crazy !! The shaft and head of the penis is also sensitive, particularly the edge of the penis 'helmet'. Someone running their tongue up the underside of a man's dick is also a good way to make him 'hard'.

Sorry but, I'll copy paste my answer from a website:
Penis — The penis is the male organ for sexual intercourse. It has three parts: the root, which attaches to the wall of the abdomen; the body, or shaft; and the glans, which is the cone-shaped end of the penis. The glans, which also is called the head of the penis, is covered with a loose layer of skin called foreskin. (This skin is sometimes removed in a procedure called circumcision.) The opening of the urethra, the tube that transports semen and urine, is at the tip of the glans penis. The penis also contains a number of sensitive nerve endings.
The body of the penis is cylindrical in shape and consists of three internal chambers. These chambers are made up of special, sponge-like erectile tissue. This tissue contains thousands of large spaces that fill with blood when the man is sexually aroused. As the penis fills with blood, it becomes rigid and erect, which allows for penetration during sexual intercourse. The skin of the penis is loose and elastic to accommodate changes in penis size during an erection.
Semen, which contains sperm, is expelled (ejaculated) through the end of the penis when the man reaches sexual climax (orgasm). When the penis is erect, the flow of urine is blocked from the urethra, allowing only semen to be ejaculated at orgasm.
Scrotum — The scrotum is the loose pouch-like sac of skin that hangs behind the penis. It contains the testicles (also called testes), as well as many nerves and blood vessels. The scrotum has a protective function and acts as a climate control system for the testes. For normal sperm development, the testes must be at a temperature slightly cooler than the body temperature. Special muscles in the wall of the scrotum allow it to contract and relax, moving the testicles closer to the body for warmth and protection or farther away from the body to cool the temperature.
Testicles (testes) — The testes are oval organs about the size of large olives that lie in the scrotum, secured at either end by a structure called the spermatic cord. Most men have two testes. The testes are responsible for making testosterone, the primary male sex hormone, and for generating sperm. Within the testes are coiled masses of tubes called seminiferous tubules. These tubules are responsible for producing the sperm cells through a process called spermatogenesis.
Epididymis — The epididymis is a long, coiled tube that rests on the backside of each testicle. It functions in the transport and storage of the sperm cells that are produced in the testes. It also is the job of the epididymis to bring the sperm to maturity, since the sperm that emerge from the testes are immature and incapable of fertilization. During sexual arousal, contractions force the sperm into the vas deferens.
What are the internal reproductive organs?
The internal organs of the male reproductive system, also called accessory organs, include the following:
* Vas deferens — The vas deferens is a long, muscular tube that travels from the epididymis into the pelvic cavity, to just behind the bladder. The vas deferens transports mature sperm to the urethra in preparation for ejaculation.
* Ejaculatory ducts — These are formed by the fusion of the vas deferens and the seminal vesicles. The ejaculatory ducts empty into the urethra.
* Urethra — The urethra is the tube that carries urine from the bladder to outside of the body. In males, it has the additional function of expelling (ejaculating) semen when the man reaches orgasm. When the penis is erect during sex, the flow of urine is blocked from the urethra, allowing only semen to be ejaculated at orgasm.
* Seminal vesicles — The seminal vesicles are sac-like pouches that attach to the vas deferens near the base of the bladder. The seminal vesicles produce a sugar-rich fluid (fructose) that provides sperm with a source of energy and helps with the sperms’ motility (ability to move). The fluid of the seminal vesicles makes up most of the volume of a man’s ejaculatory fluid, or ejaculate.
* Prostate gland — The prostate gland is a walnut-sized structure that is located below the urinary bladder in front of the rectum. The prostate gland contributes additional fluid to the ejaculate. Prostate fluids also help to nourish the sperm. The urethra, which carries the ejaculate to be expelled during orgasm, runs through the center of the prostate gland.
* Bulbourethral glands — The bulbourethral glands, or Cowper’s glands, are pea-sized structures located on the sides of the urethra just below the prostate gland. These glands produce a clear, slippery fluid that empties directly into the urethra. This fluid serves to lubricate the urethra and to neutralize any acidity that may be present due to residual drops of urine in the urethra.
