The ONLY valid way to measure your dick length is to take an old-fashioned wooden school ruler, place it flat on TOP of your dick, and push it into your pelvis as far as you can. Looking down from above, where your dick ends is how long your dick is.
Read it and weep. It does not get any longer than that.
*note: If you are uncircumcised, pull your foreskin back before measuring, it will pull back inside the woman and does not count as length. Sorry.
Girth is a technical term that means "how big around it is." Not the width, not the diameter, but the circumference.
To measure girth, wrap a carpenter's measuring tape ONE TIME around the shaft of your cock - NOT the head, but the shaft. If you dont have that kind of tape measure you can use a bit of string or even your ipod power cable for all i care, just mark the part where the string comes round to finish its circle and then measure that on a ruler.
That is your girth.
To give you an idea of what's "average," five to six inches length is considered "average." A majority of women find that to be perfect, as long as the dick owner has a clue of what he's doing. If he does not know, then dick length is totally irrelevant, because he's a lousy lay, no matter what.
If you are shorter dicked than average, you may have to work on having a nice personality and good sexual techniques. Do that, and you'll be getting more ass than a ride at Six Flags. if you are longer than average? Same thing. The ONLY person who gives a shit about your freak-of-nature footlong schlong is YOU. Be a nice person and a good lover, or get used to jacking off. Jacking off ALL THE TIME.
A standard 12 oz beer can (Miller, Bud, NOT Coors) is approximately 8 inches in girth. So if you claim a "beer can dick" you better be close to this. A "beer can" dick is probably too fat to fully enjoy. Don't believe me? In the privacy of your own home, try wrapping your lips around a beer can.
Next measure -- a paper towel roll. A paper towel roll -- exact same size as a toilet paper roll -- is just shy of 5 1/2 inches in girth. Again, in the privacy of your own home, maybe the next time you're sitting on the toilet jacking off (that may be right now for some of you), see if you can put your dick inside the toilet paper roll. If you can, then your dick girth is LESS than 5 1/2 inches.
