I assume you mean interfere or cause some sort of problem with growth. It will not hurt a thing. Male or female, there is nothing wrong with masturbating and pretty much everyone does it.
you are still growing
It gets bigger while the rest of your body does. When you stop growing, so does your penis.
Your penis will probably stop growing around age 16-18. If you are in your late teens, and your penis is still noticably smaller than average (see related link), you might want to see your doctor to be sure that you have, indeed, had your growth spurt. but scientifically there is no set age for the penis to stop growing. The penis will stop growing at the same time the body finishes growing a few years after puberty finished. This averages out at around 20-years-old.
Strange question. Yes you can get infected by the penis. But HIV once caught HIV is in your whole body, and not restricted to a single part.
Usually with the penetration of a penis stuck into the lady's vagina. Wow! sex
It is spread through infected bodily fluids, and it usually enters through the penis or the vagina, but it can pretty much enter anywhere.
It is Puberty. During this period of time in a boys life the penis and testes begin growing, amongst other parts of the body. Sometimes the testicles will look bigger and hang lower than the penis, this is all part of the growing and normal. The penis will catch up and grow longer so don't worry about a thing.
At that age you are in puberty and growing at a new level. Parts of your body may grow at a different rate to others during growth spurts. The penis will grow and keeps growing until you stop at around 20-years-old. The average adult penis size is between 3" and 4" flaccid and 6" erect.
As a virtual assistant, I do not have a physical body or the ability to grow body parts. If you have any other questions or need assistance with something else, feel free to ask!
no, I'm also 15, and my body grew a lot during time, but my penis and testicles don't. Wait some months, now my penis and testicles are really big, (penis: 25cm). Wait Th time to pass, so you will have really fun then. I'm ejaculating now!!
Yes, the penis is considered an organ in the human body.
That's normal at the very start of puberty the balls grow and start producing hormones which make the rest of the body changes of puberty
