5 to 6 inches. According to a 2013 study published in the Journal of Sexual Medicine, the length of the average guy’s penis when erect for men living in North America is 5.6 inches.

False. When it comes to flaccid and erect penis lengths, men differ a lot. Some are “growers”. Some guys have a penis that is rather small when soft but will grow considerably bigger, even double in size, once erect. Others are “showers”. They have a penis that appears large when soft but does not gain much in size when erect.

True. While circumcision remains a topic for debate, there are some health benefits associate with circumcision. Men who are circumcised, that is do not have foreskin, are less likely to acquire HIV as a top, and are also less likely to contract herpes, syphilis, genital warts, and cancer of the penis.

Tail. “Penis” or penes comes from the Latin word pene which means “tail.” Penis is pene + s, where the “s” is a common male nominative suffix in Latin.

False. In most cases, penis curvature is normal. It is common for a penis to curve slightly to the right or left, or upwards or downwards when erect. However, a curved erection of more than 15 degrees from the midline can indicate a problem such as Peyronie’s Disease. Men with Peyronie’s disease may experience painful erections, inability to maintain an erection, or have difficulty during sex due to the curvature of their penis. If the hanging or curvature of your penis is causing pain and/or problems during sex, you should make an appointment to discuss the issue with your doctor.

30%. According to a 2007 report by the World Health Organization, 30% of all men aged 15 and older are circumcised. The prevalence of circumcision, however, varies greatly based on geography, culture, and religion. For example, circumcision tends to be more common in North America compared to Europe. Additionally, Jewish and Muslim men make up approximately 70% of all circumcised men.

True. Well, true at least according to a 1999 study published in the Archives of Sexual Behavior. In this study, men were asked to report the size of their penis. However, no one measured the guys’ dicks to verify what was reported. That said, gay guys were more likely to report larger penis lengths and circumferences than heterosexual men. Not sure though whether gay guys over estimated their dicks, or straight guys underestimated theirs, or whether gay guys really do have bigger cocks.

45 km/hr. The average cum shot fires out at a speed of 45 km per hour. However, the record for the fastest recorded ejaculation is a speedy 80 km per hour. My question is, who was the lucky person who got to measure cum velocity from a whole bunch of guys?!

There is not much you can do to increase the size of your penis. You should enjoy your penis whatever its size. That said, some guys do undergo penis enlargement surgery. However, these procedures are often expensive and have risks. They generally add less than an inch in length, and while they can make your penis thicker, the risks from this surgery include chronic pain, decreased sensation, and development of scar tissue.

However much you want. Essentially, there is no “normal” or “healthy” recommended amount of masturbation. And, of course, the frequency of masturbation will likely increase or decrease depending on what else is going on in your life. Many guys find they masturbate more when they are on vacation and feel relaxed, and perhaps masturbate less during periods of stress. Fortunately, it’s not about how many times you masturbate daily or weekly, but about how masturbation fits into your life. As long as masturbating doesn’t cause significant disruptions in your life like missing work, you should feel free to masturbate as little or as much as you like.

None. Believe it or not, although it is called the “love muscle”, your penis doesn’t contain any muscles. Men who can “flex” or move their penis when erect are contracting their pelvic floor muscles to do so, and are not contracting muscles in their penis.

The average load of cum is 2-5 mL, or between half and one teaspoon.  If you stimulate your  penis or “edge” for a while before cumming, you may find your load will be bigger. It is perfectly normal for the amount of cum you produce to decrease as you get older.
