You get a penis enlarging surgery.
If your penis is already 7 inches long at 15 it probaly started growing early on in puberty and may have already finished growing. Howver if it began growing late in puberty it might still have some more growing to do. The average length of an erect adult penis is 6 to 7 inches so even if yours doesn't grow any more it is already a decent length and if it does grow longer penis of 8, 9 and even 10 inches length are not uncommon.
No It does not have any effect on the growth of the penis at all. as it does not restrict the space it has to grow in. the foreskin grows itself in any case and is made from a form of tissue that is able to stretch a great deal more then the size any penis would grow too. I believe it would, seeing as it would give it more room to grow.
i lil bit maybe
No. Nor are there any exercises which will increase size
It stops growing when your around 20
It can be any size but average is 5-6 inches for an adult.
It will definatly grow. if its 2 inches flaccid then its fine if it is 2 inches erect you have not started puberty or you are in your early stages of puberty. I'm 13 and my penis is 4 inches erect so that is double yours, but when i was in my very early stages of puberty mine was 2 inches too. im surfpebble im 13 and my penis is 4 inches erect also and im 4'9 tall so people are always sayin that if your short you have a smaller penis but that is not true im as tall as a 11 yr old and i have a standard size penis for being 13 yrs old if you have any personal questions msg me
Any size really. It can be grow to be about 12 inches tall or even more.
Milk helps your body grow. It won't help your penis grow but it won't do any harm.Most penises grow a bit when you go through puberty. The average is less than six inches erect, so don't worry too much.milk makes everything in your body grow, it makes your eyesight better and lots of things strong.
sorry but no. once you masturbate it relases hormons that tell ur body to stop growing more penis because you got laid and that means its ok length for girls but that's not true you just whacked off and that means you won't grow any more.
