The circumcised penis. The frenulum, or frenum, is a connecting membrane on the underside of the penis, similar to that beneath the tongue. If the circumcision was performed as an adult, the keratin layer will form, and the sensitivity of the glans will gradually be reduced over time. If the surgery was performed on an infant, by adulthood a relatively thick keratin layer will have formed on the normally skinless mucosal surface of the glans, which further reduces the stimulation. The surface of the glans has developed a thick, dry layer of keratin toughened skin , which makes it less sensitive to unwanted stimulation, but also less sensitive to the more subtle qualities of lovemaking. This is not an indication for circumcision, because there are good alternative treatments available that preserve the structure and function of the foreskin.

When unfolded, the prepuce is large enough to cover the length and circumference of the erect penis and acts as a natural sheath through which the shaft glides during coitus. Intact penis hidden structures shown. When fully retracted, the foreskin is designed to cover essentially the entire penile shaft, yet is loose enough to "glide". When the penis is not erect, it tightens to narrow the foreskin opening. Doctors usually do not provide this information.
