search for the "functions of foreskin" (there is already a question about it at this site) and for an article in mothering 1997 with a list of functions (or purposes call it benefits if you wish.)
would you throw away something with value?
No a foreskin is there to protect the Glans and to keep it moist.
If you're NOT circumcised, you can be afraid of foreskin problem.
You need to see a doctor for this problem.
This could be a relatively rare but not serious medical problem -- sometimes the opening of the foreskin just isn't large enough. Circumcision will fix this problem, but there are other surgical solutions if you want to retain your foreskin. Your doctor will probably prescribe medication after the surgery to suppress your erotic response until things heal. It sounds as if you may not be circumcised. Go have a good check-up by your doctor and discuss this problem with him. Don't be embarrassed as many men have this problem (your own doctor may have had this problem.) There are many things that can be done to deal with this. Having sex shouldn't hurt you so please get it looked after. Nothing terribly wrong, but obviously you are not comfortable with it and you can have it corrected. Sometimes it's a matter of exercising the foreskin believe it or not.
You don't necessarily have a problem - circumcision has NO age limit.
A tight foreskin is somewhat common in uncircumcised men. It is a problem that can easily be fixed without circumcision. The opening of the foreskin can be gradually stretched using a combination of stretching exercises and a topical medication. You can learn about how to stretch your foreskin by searching on Wikianswers for "How do you stretch your foreskin?" Gradual stretching works in about 95% of cases and allows you to avoid circumcision, which has a painful two to three week recovery period.
The foreskin may also be referred to as the prepuce.
No not at all except if you already have got a loose foreskin it became to loose and will not stay behind the head of the penis.
No when they circumcise they remove the foreskin only. Not the penis.
In circumcision of infants, the foreskin is pulled tightly into a specially designed clamp, and the foreskin pulls away from the broadened tip of the penis. Pressure from the clamp stops bleeding from blood vessels that supplied the foreskin
By examination of the word 'long' one would assume the question is referring to a foreskin greater than average. Average foreskin covers the glans of the penis completely when soft. When erect average foreskin typically slides back and exposes some if not all of the glans. If a man has 'long' foreskin, by description alone it suggests that the foreskin is of a greater/longer amount than average. Some men with longer foreskins can have an erection with no exposure of the glans. In other cases the foreskin can be long enough to cover the glans during erection with excess at the tip. Typically the position of the foreskin is dependant upon the elasticity and size of the frenum, which attatches the foreskin to the underside of the glans. The more flexible and abundant the frenum is, the more likely the foreskin is able to slide up and down.
Yes it is a problem but not one that cant be overcome The foreskin and the glans of the penis are designed to work together. that means when you are having sex the foreskin actually rolls backwards and forwards over the glans of the penis. The glans are very sensitive and are responsible for much of the pleasure in sex and masturbation however so is the foreskin and when their mucous surfaces rub over each other it is extremely stimulating for the man. this movement of the foreskin over the head of the penis is also a pleasure for his female pardner. So you should endeavor to loosen your foreskin. Al you need do to get some info to get you started it to go to the top of this page and ask "how do you loosen your foreskin" and all will be revealed.This is fairly common among uncircumcised men. Sex may be painful, but if a condom is used (which one should be used anyway) it will prevent any discomfort.I don't know if sex is less pleasurable, but I know that if there is less stimulation that could be a blessing in disguise as it could help the man last longer which should make everyone happier.
Circumcision prevents the accumulation of smegma under the foreskin. Smegma has an odor. Therefore if that is the cause of the issue. It will remove it. If the odor is caused by something else it won't. On balance it probably is. It is likely that you have some sort of infection that needs treatment as a healthy penis with or without smegma should not stink. If you are intact and your foreskin is uncomfortably tight but has been retracted then simply doing some foreskin stretching exercises will alleviate your problem.
