very little
You dont.
Sizes will vary
If your penis is five inches long, then you have already started puberty. The normal size of a pre-pubertal penis is around 3cm, which is about 1 inch.
Anywhere between 5 and 8 inches erect...
Not necessarily, no. Many boys start puberty late in life, and there is no direct link between the age it starts, and the final outcome regarding penis size.
it will probably not grow anymore, unless you are one of those that has long or delayed puberty. during puberty is really the only time that your penis grows noticably
When in Puberty the boys penis will grow longer and thicker.
Normally when boys go through puberty they get hair under their arms (armpit area), they get hair around their genital area and their penis or genitals get larger. Their voice deepens and they begin to want to have sex all the time. Often they will wake up and have an erection because of dreams. All of this is normal. To answer your question, yes your penis should grow at least a little more when you start to go through puberty.
puberty
it makes your penis have spurm
Definitly. Most people have several inches added to their penis lenghth during puberty don't worry it will be much bigger than it is before puberty.
Size doesn't make you a man. Plus your penis and testes will stop growing at age 21. So stop worrying.
