Four inches is a bit below average length however it is enough to have sex quite effectively. The only real difference is that you have to be a bit more care full that you don't come out on the backward stroke. However depending on your age the situation may still change. And above all it is not the size of the penis that decides the quality of the lovemaking.

Depends on whether your penis is erect or flacid. Also, if you are Chinese I wouldn't worry - you're ahead of them in terms of penis size.
There is nothing wrong with having an 8 inch penis, though large for your age just enjoy it.

It depends if your penis is erect of flaccid. A 3 inch flaccid penis is average, however a 3 inch erect penis is slightly below average for a 14 year old. We cannot say what size it will be when you're 21, as penis' develop at different rates.
