****************************************
The external sex organs of men are the penis and the scrotum. The penis is a sensitive organ important to reproduction and urination and to sexual pleasure. At its tip is the glans, which contains the urethral opening, through which urine passes. The ridge that separates the glans from the body of the penis is called the corona (Latin for “crown”), or coronal ridge. The glans and the corona are the most sensitive parts of the penis. The glans is covered with a foreskin (prepuce) unless the man has been circumcised, in which case the foreskin has been surgically removed.
The penis contains three cylinders of tissue that run parallel to the urethra. During sexual arousal, these tissues become engorged with blood and expand, causing the penis to enlarge and become erect (erection or tumescence). Men do not have a penis bone or a muscle that causes erection, as do some other animals.
The scrotum is a pouch that hangs below the penis and contains the two testes, which produce sperm (the male sex cell responsible for fertilization) and are considered part of the internal genitalia. The testes also are the primary producers of testosterone (male sex hormone) in men. Inside the testes are about 1,000 seminiferous tubules that manufacture and store the sperm. The scrotum can pull up closer to the body when the surrounding temperature is low and can drop farther away when the temperature is hot in order to keep the testes at an optimal, constant temperature somewhat lower than body temperature.
After sperm are produced, they move out of each testis and into the epididymis, a long tube coiled against the testis, where the sperm are stored and mature. The vas deferens transports the sperm from the epididymis through the prostate, after which the vas deferens becomes the ejaculatory duct. Here, fluids from the prostate and seminal vesicles (small sacs that hold semen) combine with the sperm to form semen, a thick, yellowish-white fluid. The average discharge of semen, called ejaculate, contains approximately 300 million sperm.

Yes, it is important to have a working knowledge of the reproductive system of both sexes. However, I don't see the connection between knowing "the anatomical organs and physiological components (both internal and external), as well as to list their individual etiology and biological functions without recourse to a text book" and having an opinion on "male sexuality and masculinity." Certainly you are not inferring that male sexuality and masculinity begins and ends with the male reproductive organs? That the sum total of a male's being, sense of identity and sexuality is the working bits between his legs? If this is what you are truly saying, then you are truly insulting men.
Sexuality and masculinity go far beyond the reproductive system. There are psychological, sociological, ethical, philosophical, cultural and esthetic dimensions to a person's sexuality and sense of gendered identity. We are complex beings in many ways, not just in regards to our reproductive systems.

Actually that was one of my more enjoyed microscopy labs in university, testicles have the most AWESOME patterns under a microscope. Seriously if I were a fashion designer, I'd put that print on fabric!
Human Male Reproductive System (pretty much the same as any other mammal):
Macro-Anatomy and Physiology:
THE PENIS
Glans - head of penis, contains most nerve endings
Foreskin - covers glans when present
Urethra - tube connecting bladder to outside, used for urination, exits the glans, also carries seamen during ejaculation
Shaft - the "long part" made up of HIGHLY vascular spongy tissue which retains blood to achieve erection.
Bulbe - true "base" of the penis, the end of the internal part, felt between scrotum and anus.
THE "SAC"
Scrotum - external skin holds the testes and regulates temperature
Testicles - produces sperm, testosterone, and some fluid
Epididymis - stores sperm, a coiled tube.
Vas Deferens - tube from Epididymis to urethra, sperm high way
GLANDS
Prostate - produces much of the fluid in seamen
Seminal Vesicle - produces fluid in seamen (sugars)
Cowper's Gland - produces fluid in seamen and pre-ejaculate
There are more things but that's all I remember. No books used, but I did check my spelling. How did I do?

Biology is my forte, and one of my best classes was Anatomy and Physiology (my prof could not believe I was taking the two semester course for fun...thought I was a pre-med student), so yes, I can list the anatomy, physiology, and the hormones that run the male reproductive system.
I am not going to sit here and write a virtual book, however, but I find it rather silly that you think every woman should be able to give such detail when a lot of men don't even know all the details. At that, how many people out there know the names of all the bones in their body? or the foramen in their skull? or where all their organs are?
Unless they have an interest in medicine or anatomy, a lot of people cannot stand up to your test.
I will, just for the hell of it, list the pathway of sperm for you: seminiferous tubules, epididymus, vas deferens, ampulla (where seminal vesicle fluid is added to the sperm), passes the prostate and gtes a dose of prostate fluid on its way to the ejaculatory ducts, finally forced through the urethra and out of the penis.

Like you I have spent decades as a nurse and am very well educated about this area. I know most others are not. Men do not understand the importance of knowing their own bodies and should be encouraged at all times to do testicular examination, breast checks and have a health care professional check their prostrates.
Men must be proactive when it comes to health and women should be more aware of the problems that males may encounter so that they can be supportive and encourage and suggest viable solutions. An example would be to insist everyone visit doctor every six months for a check up for preventative measures.

Others have covered some of the basics, so I thought I'd just point out a few things people missed:
a) The corpus spongiosum. Located in the shaft of the penis. This is the part on the sides that feels a little "squishy" even when the penis is erect. The analogous part in the female is located under the labia minora, and can cause them to appear "puffy" when she is aroused.
b) The corpus cavernosum. This is the center part of the shaft, which is NOT "squishy." It expands enormously as it fills with blood.
c) The crus, which follows the angle of the pubic bone.
Oh, and a nifty fact: The testes are actually considered "retroperitoneal" (like the kidneys) because they take a little bit of the peritoneal sac with them when they descend. Woohoo!

Probably not everything, but the male body is very fascinating, a work of art(as well as a womans). But why do all women have to name everything with the male reproductive system anyway? I'm not interested in posting about mens sexuality and masculinity, as I'd rather hear it from men themselves.
Can all men name everything about the womans reproductive system without looking at any references?

um...seems you've got your cremasters all up in a bunch.
i don't know why you're so incensed about other people's OPINIONS (however ill-educated those opinions might be) as everyone is entitled to their own. but if they offend you that much maybe you should take some time to consider why you're taking offense and not attribute feminism (and i assume such because you are only addressing your questions to women--i'm sure many men do not know the finer points of how their boy-parts function) as a lack of understanding or envy of male anatomical and physiological minutia.

Hi Ashleigh. In answer, yeah, I know the Male Reproductive System. Nice that you've learned it, as well.
In reality nothing is learned, nothing gained. In order to prevent ingrown hairs; shaving the male/female glans is a bad idea unless you're paid for it, and those big lumps - if you do - are probably not cancerous. Hair is shaped, not shaved. Number One killer of sexuality in society today. Always wanted to say that. (An aside: Brittney Spears - Are you listening?)
Did you know you can pee through an erection? Real anatomy.

I've taken a couple of anatomy classes, but I'm sure I've forgotten quite a bit. I might get a B- or a C.
