In male human anatomy , the foreskin is a double-layered fold of smooth muscle tissue , blood vessels , neurons, skin , and mucous membrane that covers and protects the glans penis and the
urinary meatus . It is also described as the
prepuce , a technically broader term that also includes the clitoral hood in women, to which the foreskin is embryonically homologous . The highly innervated mucocutaneous zone of the penis occurs near the tip of the foreskin. The foreskin is mobile, fairly stretchable, and acts as a natural lubricant .

Yeah, that's from wikipedia, you can continue reading from there.

I believe 80% of we Nigerians were circumcised and I think it ain't fair to us by our parents for hindering us to make a choice on our own.

here are some of the benefits of being intact (uncircumcised)

1. The foreskin is the natural protective covering for the glans, or head of the penis. It prevents the surface of the glans from becoming thickened and desensitized.

2. The loose foreskin covers the longer shaft of an erect penis. It is long enough to slide (glide) back and forth, facilitating intercourse as nature intended.

3. The foreskin plays an integral part in sexual pleasure. Recently described in the medical literature, a series of tiny ridged bands on the inner surface of the foreskin contribute significantly to sexual pleasure.

4. An intact man can choose as an adult, with fully informed consent, whether or not he wishes to have his foreskin removed. A man circumcised in infancy has no such choice.

5. An intact male does not suffer, as an infant, the pain of circumcision.

6. An intact male does not have to wonder why someone else removed a normal, useful part of his sexual organs.

7. An intact male has skin to cover his glans penis which, in all mammals, is an internal organ.

8. An intact male will never have to consider spending years trying to stretch what skin he has over his glans penis.

9. The overwhelming majority of intact men thank their parents for keeping them intact.

10. Intact men do not have their basic human rights (to an intact body) violated. By not having him circumcised, you can give your son a gentle beginning, the gift of his whole body, and all the sensitivity and feeling that nature intended.

The question here is, will you circumcise your child, or give him a choice to choose ?
