There's no real correlation between the size of a man's hands and his penis size.

Although folklore abounds comparing the size of a man's hands, his feet, the length of his nose and his fingers, to uh, more private parts of his physiques, there is nothing at all to any of these theories. Many men who have big hands and feet do indeed have large members, but it's just as likely that a man with a big penis has small hands. Or vice versa.

The results of a study of 104 men with foot sizes eight through 13 surveyed and examined at St. Mary's Hospital and University College Hospital in London published in the British Journal of Urology International reported that there is no link between foot size and penis thickness or length, stating there is no medical evidence to support this widespread, long-held foot-penis size theory.

Even so, human beings want to believe. We want to see patterns even where none exist to assume the human body was built on a precise scale. But Mother Nature defied this notion by coming up with random patterns. The only halfway reliable way to gauge a guy's penis size before you've felt or seen it is to listen closely to what the guy says about it. For example, guys who immediately own up to their small penises often really have little ones. And many guys who brag and strut around as God's gift are often well-endowed. (Unfortunately, these guys often have enormous egos; in which case, you'd be better off dating the guy with the small penis who has a dexterous tongue!)

Sometimes too much of a good thing can be a bad thing!

Yes. Excessive, persistent, intense sexual needs, urges involving nonhuman objects, and a need to masturbate constantly, are all considered psychological disorders! A fixation on masturbation is a compulsive sexual behavior, says the Mayo Clinic. Compulsive sexual behavior is known by other names such as hypersexuality, nymphomania, or erotomania. Some docs and shrinks call this behavior a sexual addiction, comparing it to the uncontrolled use of a drug. Some medical experts call excessive masturbation an issue of impulse control.

So how can you tell if you're playing with yourself too much? Here are the main questions: Does your pleasuring routine interfere with your job? Would you rather stay home and masturbate than have a real social life or relate physically to your partner? Is staying home with your porn more important than hanging out with your friends? Do you spend as much time as you can at work on the DL, furtively touching yourself while looking at smut on the web? If you've answered 'yes' to even one of these questions, you're masturbating too much.

About 30 percent of males in the world are circumcised.

Male circumcision is the surgical removal of some of all of the foreskin or prepuce of the penis. The word comes from the Latin word caedere, which means "to cut." While the practice is very old (there are cave drawings depicting it), circumcision is a religious commandment for those who practice Judaism or who live by the rules of the Islamic culture. Circumcision is also a requirement of the Oriental Orthodox Christian church in Africa. According to the World Health Organization, about 30 percent of males in the world are circumcised. At the same time, human foreskin is a highly innervated, vascularized, sensitive erogenous zone. It would seem obvious that removal of the foreskin interferes with sexual function and pleasure, and yet studies abound for and against circumcision.

The Centers for Disease Control in 2008 cited evidence that male circumcision significantly reduces the risk of HIV, and at the same time clearly noted that the procedure provides only partial protection and should not replace other interventions known to prevent transmission of that disease. Research from the American Academy of Pediatrics, the Masters and Johnson Institute and the American Academy of Family Physicians suggests there is little discernible difference in experiencing pleasure between circumcised and uncircumcised males.

Nevertheless, a preponderance of anecdotal evidence is published on and off the Web decrying the practice of what many call "the unkindest cut of all." Citing that the genitally intact male has thousands of fine touch receptors and other highly erogenous never endings, it would seem that these pleasure-producers would be lost to circumcision. But since anti-circumcision studies are often biased, and much of the medical literature on the subject is contradictory, at the end of the day, sexual pleasure remains a personal and highly subjective emotional, physical, psychological, even spiritual, experience.

Most women are indeed hornier when they're fertile.

Makes sense, right? This is nature's way of telling them that their body is ready to get pregnant. The ovulation stimulates the hormones and triggers sexual excitement. Also many women find that their nipples are more sensitive and they're more responsive to touch while they're ovulating. During ovulation, when the female body is most receptive to the man's seed, the women's basal body temp rises, making her literally hotter. Biologically speaking, most women feel that their sex drive kicks into high gear during ovulation at mid-cycle, or about fourteen days before they're due to get their next period. Surges in estrogen plus added testosterone that comes with ovulation might explain why the libido is heightened.

If you look at it in terms of evolution, it makes a lot of sense. Nature designed the female body for reproduction, so if she grabs you and wants to make love and it's her fertile time of the month, go for it. She could be an animal in the sack! Just don't get carried away by her ardor and forget about birth control unless you want to make a baby.

It takes up to four hours of vigorous sex to burn off the calories in one slice of pizza.

While there's a widely held belief that a half hour of energetic sex burns the equivalent calories in a slice of pizza, it's just not true. Let's look at the math: A half hour of vigorous sex burns about 85 calories, and most diet Web sites say that a slice of plain cheese pizza is about 230 calories, while a slice of pepperoni is about 290 calories. So, it's pretty clear that it takes more than 30 minutes of active lovemaking to burn off a single slice. Even guys on Viagra can't have sex for hours on end, so don't count on that to help you lose weight -- unless your motivation to lose weight is to look better while having sex. In which case, simply nix the pizza!

When presented with sexy pictures, men are more likely to focus on a woman's face and woman focus less on faces than body parts.

Dr. Heather Rupp is a leading author who analyzes the viewing patterns of men and women looking at sexual photographs. New material she's recently published in the Kinsey Institute Journal reveals the results of that study, which are definitely not what you might think.

Researchers who studied the different ways men and women approached pornography hypothesized that women would look at faces in the photographs and men would look at genitals. Wrong! Instead, they discovered that it's men who are more likely to look at a woman's face and that women focus less on faces than particular body parts! An even bigger surprise was that it turns out women look longer than do men at pictures of men performing sexual acts with women.

The study also confirmed that men and women looking at the same sexual material show different patterns of brain activity. "Men looked at the female face much more than women, and both looked at the genitals comparably," said Dr. Rupp. The data also suggested that women's responses varied according to their hormonal state, with women on oral contraceptives paying more attention to genitals than other women in the study.

When a woman licks her lips, it means she is horny.

In fact, she might be so horny she has no control over her involuntary gestures, like her mouth going all dry at the very sight of you. Or she may be licking her lips deliberately, twisting her mouth into a big O and then running her tongue all around it in circles to show you what she intends her tongue and lips to do to you. For a less openly sexual girl, the lip licking could also just mean that she's very attracted to you, that she finds you a hot and sexy heartthrob. Or it could mean that she's a little nervous, that she's a bit discomfited by you, that your presence makes her jumpy and has turned her dry-mouthed. In fact, she could use a glass of water. Dry mouth, incidentally, is a sign of sexual tension, a body language thing where the body tells the mind there's something going on here.
