The skin that covers the glans or head of the penis which is removed during circumcision is called the foreskin or prepuce. Its main purpose is to protect the glans from heat, cold, and dust. With the advent of clothing, such protection though is no longer necessary. But we still need to be thankful to nature at least it has provided us with some sort of protection.
An uncircumcised male will have his foreskin extending over his penis’ head. Oftentimes, the excess skin can be very long that it nearly covers a third or half of the total length of the penis’ skin. The foreskin of an uncircumcised penis may actually look just like an ordinary skin, but in truth, it is filled with many blood vessels and nerve endings. Inside the foreskin on the other hand is similar to our mouth that it helps keep the glans naturally lubricated.
The head of the penis is connected to the foreskin by the tissue ‘frenulum.’ This tissue is very much similar to what connects our tongue to its base. The frenulum however can contract and relax. Once the penis becomes hard, the frenulum relaxes thus increasing the opening of the foreskin and allowing the head to go out. If the penis is flaccid, the frenulum contracts making the opening of the foreskin much narrower, thus increasing its protective quality over the glans.
The foreskin’s length differs with each person. Some men have foreskin that completely covers and exceeds that of their penis’ head. Some on the other hand only have foreskin that covers part of their penis’ head. There are others though who are deemed naturally circumcised because the foreskin of their penis only covers their shaft. However, this is only during erection so hygienic practice is still necessary during flaccid state.
As mentioned earlier, there are actually many nerve endings located inside the foreskin. These nerve ending are able to provide added sensation and stimulation which medical researchers believe can make sexual intercourse way more pleasurable. The frenulum in addition can also add more to this sensation.
Even if the foreskin may actually provide you with more sensation than without it, one would beg to question if this is enough to keep it when the complications that it brings are numerous. The foreskin tries to keep the glans cool by keeping it moist. However, this moisture can be prone to bacteria buildup especially if regular hygiene is not maintained. Such poor hygiene can lead to urinary tract infection or the buildup of smegma, a whitish nasty smelling substance evident of unhygienic practice.
There are actually several cases where the foreskin is subjected for circumcision. Such would include phimosis, a condition where the foreskin is too tight during erection. Paraphimosis, a condition where the foreskin slide down the penis’ head and will not on its own return back. Balanposthitis, an inflammation on the inner part of the foreskin (the lubricating part) and require surgical removal. All of the three mentioned conditions are indicators that circumcision is necessary and must be performed.
