You will have to see a sexologist and follow him religosly.
If an erection lasts longer than 4 hours, you should call your doctor.
As long as he ejaculates in you, you can be pregnant.
Yes, and it is normal for very young children to get erections. Male babies can even get an erection while still in the womb.
For most people, there is no relationship between smoking and the firmness of the erection. (But many partners find "smoker's breath" unpleasant...)
In general, most clothing optional resorts ask that if a man has an erection in a public area, that he cover himself with a towel until the erection is over with, or to remove himself from the public view. Most public beaches that allow you to be completely nude make similar requests, though it's more strict in the United States than in Europe and other parts of the world, noting that erections happen normally in the human body all day long and are not necessarily due to sexual excitement or stimulation.
An erection "boner" is a natural function of the male copulatory organ. ....on a lighter side: A boner is a perfect knife to use if you are de-boning a chicken. It can follow the bone and allow a prescision cut and allow you to flay the meat so it has a perfect presentation on the plate. Also for fish too!
Without more information, I can't be sure if you're just talking about a normal erection or some kind of problem. All males, barring some physical abnormality, get erections, when the penis fills with blood and becomes harder and longer. This makes sexual intercourse possible, though men have countless erections without intercourse or even the possibility for intercourse. Erections can result from nearly any sort of stimulus, from a full bladder to touching the penis to thinking about someone attractive. Some people get erections from doing things which even they don't associate with bodies or sex. A lot of erections, particularly for kids, happen for no apparent reason. None of these things are abnormal in any way, and the erections simply go away on their own. If you're talking about a erection which is painful, unusually swollen (bruised or infected?) or lasts too long (4 or more hours), then something is clearly wrong and you should call a doctor IMMEDIATELY. By that I mean STOP READING and call RIGHT NOW. Leaving it for later may result in permanent damage. Means you LOVE girls
Nope, Your screwed.. (: Have fun without an erection.. :P
no
If the nerves are damaged it may not be possible to get an erection naturally
Depending on his age, health and other factors, I'd say average would be from less than a minute to a few minutes, if you are actively trying to gain an erection. If you are talking about a passive erection with no stimulation then it can take a long time.
At 14, you are supposed to get erections all the time. This is a very good thing. Be happy every time it happens. It means you are very NORMAL, and that everything inside you down there is working perfectly. You should be a happy boy. You will be having frequent erections for no reason any time any place for awhile. So be happy - but learn how to hide them. Wear baggy pants and long shirts. Relax and Enjoy you developing body - wish I was 14 again.
