Yes. For sure.
No when they circumcise they remove the foreskin only. Not the penis.
see your doctor
Partial circumcision removes only part of the foreskin. Partial foreskin may be used to treat phimosis (a tight foreskin) that does not respond to gradual stretching exercises with a corticosteroid cream. Instead of removing the entire foreskin, partial circumcision only removes the tight phimotic ring that prevents the foreskin from being retracted. Many men with phimosis prefer partial circumcision to complete circumcision as it retains most of the foreskin, which functions in several ways to increase pleasure during sexual activity.

That is perfectly normal, and nothing to worry about.
I think you are asking if you need to have a circumcision ! This all depends on how tight your foreskin is, it is not normal practise anymore to remove the foreskin unless it is needed medically. Usually it is done when you are still a child but it can be done for adults also. The foreskin should be able to move over the glans freely without causing pain. There are circumcisions on religious grounds. The Jewish faith still circumcise their baby boys. The foreskin need never be removed for any reason but to treat an existing medical condition that can not be dealt with in any other way. tight foreskins can be loosened in order for them to be able to move easily back and forth over the glans penis. The foreskin is an important part of the operation of the penis and is a or erogenous zone.
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 If you are intact and your foreskin is uncomfortably tight but has been retracted then simply doing some foreskin stretching exercises will alleviate your problem.
This is called phimosis, where the skin of the foreskin becomes tight and sometimes painful. It can be alleviated by gentle stretching and if this does not help, surgery or circumcision can be indicated.
circumcision
You may need a circumcision if you have a tight foreskin. Do not force it out as this could be very painful and damaging. If you have tried gently moving the foreskin back n forth and it will not freely go over the glans then ask to see your doctor who will be best to advise you.
If the foreskin is too tight or not, if it can be pulled back so you can clean under it.
