No, it does not. It will grow gradually.
It gets bigger at puberty, and then slowly shrinks with age.
Once you start puberty the penis will start to grow also. It will keep growing until you reach around 19 to 20-years-old. Puberty for a boy is when testosterone the male hormone is released in great amounts causing rapid growth around the body. The penis is just one part that changes during this time.
Well, men seem to worry far too much about their penis size. Any size over two inches is capable of sexual activity and female pleasure. However i will answer. Age length(inches) 10 2.5 11 2.6 (average puberty start) 12 2.8 13 3.5 14 4.0 15 4.7 16 5.0 17 5.2 18-24 5.3 (average puberty end) 24+ 6.2 From the chart above it shows the penis growth rate starting from the age of 10 to 24 years and over. The size of the penis changes during puberty. On average the growth of a healthy male penis start growing between the ages of 13 years up until 24 years of age. Some boys will start puberty later then some, but this mainly due to genetic factors.
Average male size penis is 6. Get over it and take what ya got.
It cannot be measured this way. The penis grows at its own rate throughout puberty in direct proportion to the rest of your body. Everyone is different and growth can be quick or slow depending on the genes you inherit. By the time puberty is over you will catch up with any of the quicker to grow peers.
If you are going through puberty, these new bumps may be fordyce spots, a normal part of the penis. If not, see your health care provider or family planning center for accurate diagnosis.
The penis will stop growing when puberty is over. So most boys' penises will stop growing between the age of 16 and 22. There is nothing much you can do to increase, or decrease the size of your penis. It is going to grow to the size it is genetically destined to be, regardless of what you do to it. There are not any foods, supplements, or exercises that will change the size of your penis. The only thing that changes it is the combination of hormones that occur during puberty. And then once puberty is over, it stops growing.
No, as you have said you are a "late developer" and now that you have begun to develop you should find that your height and penis length will increase as part of the process of puberty. Puberty is very variable and the normal range over which it can start for boys is from 9 years of age right up until the late teens. You have already started puberty (a while ago if your penis has already grown to 4.5 inches) so you're not actually a late developer as such, you are in fact well inside the normal range. An average adult erect penis is approximately 6 to 7 inches long and as a "late starter" of 15 years of age you probably have a few more years of puberty to go through. At 15 years of age a 4.5 inch erection is well within the normal range of penis lengths.
Puberty is a 24 hour a day process. You may be thinking of what doctors call, "Nocturnal emissions", also alled, "Night dreams". As your body turns into that of a man, you get the ability to ejaculate semen, a clear to milky liquid that carries the spermatazoa, or just 'sperm' cells that can start a pregnancy in a female. When you dream, you have sexy dreams when you are in puberty. They cause your sex organs to activate. Your penis grows hard and longer, and semen is ejaculated (squirted) through the penis. It is absolutely and 100% normal.
Before puberty the average size of a boy's erect penis is probably close to i 1inch in length while the average length of an erect adult penis is 6 to 7 inches. So, you can see that on average a boy's penis will grow 5 or 6 inches during the course of puberty (which for boys takes on average 6 years to complete). Most of the penis growth probably takes place over a period of 3 years or less but it is still too slow to spot it happening. If you measure your erection once a week and note the length you might actually be able to keep track of it's growth. Generally speaking one of the earliest changes that takes place in boys is that their testes (balls) and scrotum (ball sack) grow larger and hang lower (their balls drop). This is because sperm grow better at a slightly lower temperature than the rest of the body. So, if your balls have dropped you'll have a short period were your balls are bigger but you still have the same size penis as you've always had and then, gradually, your penis will begin to catch up.
Mine doesn't. Do you mean, "why do you get an erection looking at Oprah?" If you are still going through puberty it is quite normal for boys to get erections over virtually anything.
The white spots are hair growing. There is nothing wrong with you, you are starting puberty and your penis will grow in time.
