An anonymous writer put it this way: "Friends in your life are like pillars on your porch. Sometimes they hold you up and sometimes they lean on you. Sometimes it's just enough to know they're standing by." ©Seventyfour / Adobe StockWriter Elisabeth Foley points out that friendship doubles your joy and divides your grief, and that the most beautiful discovery that true friends make is that they can grow separately without growing apart.

If a couple tries to conceive but can’t seem to do it, one of the first things that doctors look for is a problem with the man’s sperm. Sperm compose about 5 to 10 percent of semen, and are the only part of the semen that can cause pregnancy. If a man is infertile, there is a problem with his sperm — often a low sperm count or low motility.

Many people have an idea what their measurements are, but rather than assume you know, it's best to get an accurate measurement. Going to a tailor will give you more accurate measurements, but you can certainly get a close approximation handling the measuring tape yourself.The measurements you definitely need are your chest, waist, hips, and inseam.

Knowing how a penis functions can provide useful insight into sex and the human body — whether you want to understand the penis and male anatomy better or learning about it for the first time. Basically, a penis is composed of three structures, which are made of a spongelike material that can fill with blood: The two corpus cavernosa contain the central arteries and lie on the top half of the penis.

Understanding women's sexual (or reproductive) organs such as the vagina, uterus, and vulva is as integral to sex as understanding the penis. Demystifying female anatomy is key to good sexual functioning, whether you're a mature, experienced adult or looking to learn about women's sexual organs for the first time.

Having regular prostate exams are important as a man ages. The prostate gland — located below the bladder — can become enlarged and cause increased frequent urination. This problem, called benign prostatic hypertrophy, is bothersome but not dangerous. Prostate cancer, on the other hand, can be quite dangerous if it isn’t discovered and treated in time.

Believe it or not, there is such a thing as lasting too long during sex. Retarded ejaculation (or male orgasmic disorder) is a condition in which a man can’t make himself ejaculate. Whether in a man or woman, the inability to orgasm can make sexual intercourse frustrating or even undesirable. Finding the cause is the key to learning how to fix retarded ejaculation.

Premature ejaculation is a common but stressful concern, and not just among young men. A premature ejaculator can’t keep himself from ejaculating (or “coming”) before he wants to. The cause is not physical, but mental. In other words, it’s not the man’s penis that is “malfunctioning,” but his brain. The upside is that a man can learn how to control his orgasms and avoid premature ejaculation with time and discipline.
