First of all, you should know that in a study published in BMC Women's Health, surveyed women's preferences concerning penis size and concluded that width rather than length is a more important factor of sexual stimulation.

The most sensitive area of the vagina is the section closest to the outside of a woman's body, which is roughly 10 centimeters (4 in) in length.

The walls of the vagina are composed of soft elastic folds of mucous membrane skin which stretch or contract (with support from pelvic muscles) to the size of the penis. This means (with proper arousal) the vagina stretches/contracts to accommodate virtually any size penis, from small to large.

To date, there has been no conclusive study linking penis size and race. All studies up to this point have been subject to both self selection bias and sample size flaws.

Some clinicians measure the penis by stretching the flaccid penis as far as comfortably possible. Self-reported measurements tend to be unreliable because men often want to report a larger penis size.

According to "The Definitive Penis Size Survey", the average penis size is:

VARIABLE	MODEST	AVERAGE	ENDOWED
Erect Length	141.5mm (5.6")	161.8mm (6.4")	181.1mm (7.1")
Erect Circumference	117.6mm (4.6")	127.4mm (5.0")	137.8mm (5.4")

Here is some personal data of the subjects:

• Sample size: 2,545
• Average age: 29.7yrs
• Average weight: 80.9 kg (178.3 lbs)
• Average height: 1.80 m (70.8")

That being said, it's time to find out where you stand.

The erect length is what most members are interested in. Again it is best to measure from the side of the penis. This method is the standardized method that researchers use to measure the "average penis size". Firstly make sure you have a 100% erection where you would consider it the "most erect". Hold your penis below the head and place the ruler next to it with your other hand. The ruler should be slightly pressing against your pubic bone.

Measure to the nearest millimetre and it is important that you do not exaggerate the measurement, if anything it is recommended that you under exaggerate.

Make sure your penis is 100% erect and then proceed with the measuring. Hold your penis out in front of you so it is parallel with the floor. With your other hand place the tape measure around the penis making sure not to pull too tight.

If you're average but still feel insecure about your penis size, take the next step and enlarge your penis! A men's life is about pride and honor. Why not stand out from the crowd? Isn't that the reason men go to the gym? You don't actually need huge muscles to carry out your daily chores.
