QuestionI have a question about the size of my penis. My penis is 6 inches long erect with a girth of 5.5 inches. My friend had asked me how big my penis was and I told him. He told me that his was only 2 inches long erect. Why are we so much different even if he is in a later stage of puberty than me? He will be 15 in Feburary.
You said your friend is at a later stage of puberty, but are you going by age or actual stages of development? Everyone develops at a different rates and at different times. He might be older than you but not as developed as you. Since I don't know what stage you are in or what stage he is in, I can't directly answer your question why the sizes are different.
Like other features on the human body, the size of a person's penis varies. Actually the flaccid (not erect) state of a penis varies in size constantly for a number of reasons. If you are hot, the penis tends to get longer to give more surface area to the skin and thus get rid of extra heat. If you are cold, it shrinks to reduce the amount of heat loss. If you are even slightly sexually aroused, your penis gets larger. If you are active, it tends to get smaller as the blood in your body is called for in your muscles.
The average adult penis is about 5.2 inches in length when erect, but that is just the average [http://www.bjuinternational.com/bjui-blog/normal-review-analyzes-data-flaccid-erect-penis-lengths-men/]. Typical size (what covers most of the adult population) ranges from three inches up to eight or more inches. There is no way to predict the actual size of a man's penis when he is grown. People have tried but nothing has worked with any accuracy. You might end up with a slightly bigger penis than he when you both reach adulthood. But it won't make any difference; just as he might end up with bigger feet than you. Size doesn't determine who is "better." And when it comes to the day that you marry and have sex, size doesn't matter in regards to sexual enjoyment for the husband or the wife. It is how sex is done and not the size of your equipment that makes the difference in enjoyment.
