No. Nor are there any exercises which will increase size
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
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.
You still have some growing to do in general and that should include your penis. Average adult is 6 to 7 inches and I would expect you to be in that range. There is no point in worrying about it, we all get what we get.
I do not believe that any human being has had a penis as long as twelve inches, although ten inches is possible; there are also other species which have longer penises than human beings have.
Masturbation should not cause any harm to the penis.
It depends on whether the individual has started puberty yet. If they have, there could be growth of 2 inches or more.
The average size of an erect penis is about 6 inches, or 15 centimeters. Average means then that some are bigger then 6", and some are smaller. It might be embarrassing sometimes to have a short penis, but it shouldn't prevent you enjoying sex and orgasms any less. As someone said "It isn't the size that matters, it's what you do with it!" The average penis size is 5-6 inches. No, having a 3 inch penis is not bad. It doesn't affect you physically in any manner. And it depends on your age. If you haven't begun puberty yet, then that is a normal size. * http://wiki.answers.com/Q/What_is_the_average_size_of_a_penis
Thank your lucky stars and stop whinning! 6" is good for any age. Anything more is just a waste.
The person could possibly die or grow his or her penis size 4-6 inches.
