Erections are all about physiology and psychology. If your brain is stimulated an erection will develop. That stimulation can come from any of your senses.
Some people are stimulated by music, naughty talk or the sounds of sex. The smells of sex or something that your brain associated with sex, perhaps perfume or a smell you remember from a previous sexual experience. Touch is powerful and certainly your own touch can stimulate you but likely the touch of another will stimulate you more. We are very visual creatures and seeing sexual objects or activities will stimulate you, that's evidenced by the world of porn we are awash in.
If you are young and having trouble keeping an erection, that would be a bit unusual and could be over stimulation, guilt, too much masturbation or even physical problems with your circulatory system.
There are several methods for prolonging an erection. Most of them involve thinking about something other than what you are doing (which is probably having sex, since most men don't worry about prolonging an erection at any other time) - this can be hard to do, and also frustrating because you want to think about and enjoy what you are doing. You can also try one of the many over the counter numbing creams available - they would be in the same place as the condoms in your local store. These make the penis slightly less sensitive, which can make the erection last longer. Wearing a thicker condom can also delay ejaculation, as can wearing a ring around the base of the penis (commonly called a "cock ring"). If you are having premature ejaculation during sex, you might also try changing your rhythm - slow down, go less deeply or at a different angle until you no longer feel as if you are going to lose control.
There is no such way from which an erection can be done for a long time, well there are some pills available in the market which helps in long lasting but i don't personally thing that one should try that without doctor's persciption.
When you feel like one more stroke will make you ejaculate, stop all stimulation to the penis for a few seconds and then start thrusting or masturbating again. Continue this several times and then when you are ready to ejaculate do not stop and it will be more intense.
If you want to build up your muscles so that you can hold back yourself from ejaculating, find the muscle that stops you from peeing. Act like you are stopping from peeing for 5 seconds and then relax, repeat this 100 times. If you do this daily it will strengthen your muscles so that you can go that one more stroke and hold back your semen. These steps will also increase your squirting distance and the amount of cum ejaculated.

No, as an erection is caused by the flow of blood to the penis. If a man is dead, his heart no longer works and so cannot pump blood to the penis.
Apart from chemicals such as viagra, stimulation would be the way to go.

You have an average penis size erect and it may possibly grow a little longer as you don't stop growing until you reach around 20-years-old. Be pleased with what you have.

Yes, after extended use, nipple suction does make the enlargement and elongation permanent: the nipple will not stay erect, but will stay out and function like a normal nipple--enlarging when stimulated.
