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.

As your pregnancy proceeds and your belly gets bigger, certain sexual positions become less comfortable and possibly even dangerous. Pregnant women, obviously, have a lot of temporary weight in front that can cause problems if they lie on their backs. But that restriction shouldn’t prevent any couple from enjoying sex.

The female libido can be a tricky thing, and many women experience low sexual desire (libido). Some may start out with a low sex drive, and others may experience decreased libido after menopause, childbirth, or surgery. Whatever the cause, rest assured that there are ways to increase the female libido, as long as you identify and treat the underlying cause.

The main female sexual problem, simply stated, is that many women don’t have orgasms or have difficulty reaching orgasm. Ninety-five percent of women who aren’t having orgasms are actually pre-orgasmic: they are capable of orgasm, but they need help learning how to achieve orgasm. Because every woman is different, there are no perfect tips on reaching the perfect female orgasm.

Having an orgasm is, for most people, a normal part of sex. For others, however, orgasms can slip away due entirely to the way they are thinking during intercourse. So how can you ensure orgasms during sex, solely through your state of mind? When it comes to sex, if we humans become too aware of what we’re doing, our sexual powers go haywire.

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.

If you’ve heard of only one STD, it's probably AIDS (acquired immunodeficiency syndrome), which is linked to infections by HIV (human immunodeficiency virus). Why is so much more attention given to HIV/AIDS than to any other sexually transmitted disease? Because AIDS is deadly, and it has no cure and no vaccine.

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.
