Anywhere between 5 and 8 inches erect...
very little
Sizes will vary
No and it should not be done as it can damage the natural growth of the penis during puberty.
I should hope you have hit puberty and theres something up with you!
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.
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.
I guess maybe about two or three. There is really no definite answer for that. If you have an older brother or family, have a talk with them and ask what is normal. Many people mature differently.The penis can grow several inches during puberty but it can depend on how long it was to start with also. A boy who had a smaller one will find the most growth during puberty.It can vary, but the average adult male has a penis size of between 5.5 and 6 inches.During the course of puberty, the penis will reach its adult length and girth. This usually starts at about age 11-12, although this may be later in some "late blooming" males. Puberty stops usually between the ages of 20-23 so your penis could grow from when you start slowly until you stop puberty or it can grow to its maximum during halfway thu your puberty. Your size and girth is genetic don't be shy go ask you dad brother dads side of the family their sizes youl be in that range.It really depends on the individual, especially since all teenage boys are different in one way or another, but usually during puberty a teenage boy's penis usually grows a lot in size, the average size of a grown man's penis is about 5-6 inches.Before puberty the average length of a boy's erect penis would probably be around an inch while the average length of an erect adult penis after puberty is 6 to 7 inches. So a growth in length of 5 or 6 inches and also an increase in girth (thickness) during puberty is likely.
It depends on age and whether you have been through puberty yet.
you just got to go through puberty and it should show
The penis should grow during puberty, but some people start the stages of puberty later than others. Many boys don't complete puberty until they are 17 years old. If you feel that you have completed puberty, and your penis still has not grown, then you should contact your doctor about it to see if they can figure out what the particular problem is. There are a few conditions that may prevent the penis from growing, or can cause puberty to arrest (not complete), and you want to get those ruled out, or if treated.
If you are 13, the normal length of your penis should be between 4 and 5 inches.
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.
