Difference between circumcised and uncircumcised
Also referred to as ‘cut’ and ‘uncut’, the difference between a circumcised and uncircumcised penis is on the tip of the penis. Boys are born uncircumcised, meaning there is a foreskin that covers the glans, or head, of the penis. The foreskin is a skin similar in nature to your eyelids, except located down under. Circumcision is the removal of the foreskin, after which it becomes a circumcised penis. The illustration below shows the general difference between a circumcised and uncircumcised penis. Given that a foreskin can be pulled back, the differences are often not easily seen when erect (hard), thus the illustration compares a penis in the flaccid (soft) state.
Circumcisions and foreskins are all different. Some foreskins are long, while others are short. Some circumcisions are loose (less skin removed) while some are tight (more skin removed). Some more-tightly circumcised males find it easier to use a lubricant if planning to rub the head of the penis during masturbation. Just like our faces, each penis is different.
Circumcision rates vary around the world from near universal, to even, to zero. Given how controversial this topic is, we will avoid further discussing the reasoning behind these differences. Further research can be done online if interested.
On circumcised penises, a change in shade of color along the shaft is sometimes noticeable. This is sometimes called a circumcision scar, which marks where the cut was done when the foreskin was removed. Given the variety of circumcision techniques, sometimes this shade is less/more/not noticeable. All these variations are normal.
On the other hand, on uncircumcised penises, there is a line known as a frenulum on the bottom side of the glans, or head, of the penis. This is normal, and it holds the foreskin near the glans. It serves a similar to function as the frenulum under your tongue and lips do. It is often removed during circumcision (if circumcised).
For uncircumcised males, it is important to take a few seconds to pull back the foreskin and wash under when showering or bathing. In babies and toddlers the foreskin is usually stuck to the head to avoid anything going into it, but as you age, washing under it becomes important, given exposure to sweat and ejaculate. Take one hand to pull it back and use the other to apply soap and rub; remember to rinse it off. If you’re a younger teen and had not washed much in the past, the head may be very sensitive to rub; in that case gently use water and rub lightly. As you do this more often over a week or two, it will get used to being touched by something other than the moist inside of the foreskin.
If you have difficulty pulling your foreskin back, stretching it (back/forwards/sides) and washing under it will help it loosen and separate from the head. Stretching it can take a few weeks to show results if done regularly. If stretching does not help, you may get evaluated by a physician and can ask for a steroid cream to help with the tightness. Circumcision may be done as a last resort or at your preference.
