10 inch Penis is a term loosely used on the internet. You will come across countless porno websites that talk about this elusive size (and bigger) but in most cases they will not actually deliver anything close to a 10 Inch Penis. This size is very rare, so rare that out of all of the pornography I have viewed I have only come across 2 men who actually have something close to this size. One porn actor is very famous by the name Mandingo who appears to be around this size the other is a man who goes by the name Mr. 18 (he falls about 8" short of his name) Take a look at the penis size of these 2 men to get an understanding of just how huge 10 inches is. I think you will agree that this size is more rare than the media would like us to believe.
Another good thing to look at is an actual ruler. Measure out what 10 inches is, find something around the same size and hold it in your hand. This is an eye opening experience. I have always asked men to create something that they believe is their ideal size before they even start PE, this will give you more realistic goals.
Does Penis Size Matter? When you can change your size it does. Whatever your size goals are Matters of Size will help you get there.
