YES, I am not sure of the medical term for this but in England we call it the banjo string. I know several people who have snapped their "banjo" during sex. Luckily it has never happend to me.
No when they circumcise they remove the foreskin only. Not the penis.
That is perfectly normal, and nothing to worry about.
the removal of a males foreskin on his penis
If your penis has a lump, you should see a doctor. You can't really have too much foreskin. Many mens' foreskins hang down past the head, and this is very normal.
If you cannot retract the foreskin by the age of 14, that is not normal. It could be a condition called phimosis and you should see your doctor to see how to get it corrected. When you are uncircumcised, a cheezy substance builds up between your foreskin and the glans of your penis called smegma. If not washed out properly it can lead to penile cancer.
If you are of an age that you are still growing, it may be as simple as your penis has grown a bit and the foreskin didn't. Just as every penis is different, the length of foreskin is also.
There are not 2 penises alike so how do you know it's not like others? When you were born the doctor checked and saw it was normal. If it's curved/straight, big head/small head, foreskin/no foreskin it's all normal.
Do you mean "Why is the tip of your penis inside your foreskin?" Or do you mean "Why is your entire penis inside your body?" The foreskin covers the tip of the penis to provide protection for it. A penis that is entirely or mostly inside the body is called a "Hidden" or "Inverted" penis and this condition is geneally a direct result of being overweight or obese. The penis is actually normal but is partially or wholly buried by excessive body fat. The obvious remedy for this condition is to lose weight.
The foreskin is a fold of skin that covers the head (glans) of the penis.
Circumcision is the removal of the Prepuce or foreskin from the penis. this is largely a religious practice and there are no medical or health advantages in it except in extremely rare circumstances.
A circumcised penis has the foreskin removed. An uncircumcised one does not.
Pull down the foreskin to expose the head of the penis.
