Normally, developmental non-retractability does not cause any problems, in fact, it is protective of the [[glans penis]] and protects against [[meatal stenosis]].<ref name="agarwal2005" /> Non-retractability may be deemed pathological if it causes problems, such as difficulty urinating or performing normal sexual functions, but even then, this is rare, and, if the non-retractability itself is not caused by pathological inflammation, it cannot be called "pathological" or "true phimosis."  A foreskin that is so narrow it will retract very little or not at all, but is not the result of a pathological inflammation, is accurately termed ''preputial stenosis'' (narrow prepuce), and will respond to treatment including steroid creams, manual [[stretching]], and changing [[masturbation]] habits.

The [[foreskin]] developed by natural selection over an aeon of time to provide survival of the fittest. The presence of the foreskin makes mankind more fit to survive. The foreskin is endowed with [[Immunological and protective function of the foreskin| immunological and protective functions]] to improve health and well-being. Retraction of the foreskin opens the [[preputial sac]] and allows entry of contaminants and pathogens,<ref name="fleiss-hodges-vanhowe1998">Fleiss PM, Hodges FM, Van Howe RS.

Birley et al. (1993) reported excessive washing, especially with the use of soap, will dry the oils out of tissues and cause a [[balanitis]]-like inflammation. The use of soap (including body wash, shower gel, and shampoo) should be avoided and emollients should be applied.<ref name="Birley1991">{{REFjournal

Occasionally a male reaches adulthood with a non-retractile foreskin. Some men with a non-retractile foreskin happily go through life and father children. Other men, however, may want to make their foreskin retractile.

In a few cases, the [[Synechia| synechial]] fusion of childhood lingers past puberty. After puberty, the synechial fusion should be about ready to spontaneously release the [[foreskin]] from the [[glans penis]]. One may try gently peeling the [[foreskin]] away from the glans penis by using one's thumbs. It may take one several tries to get it all separated. Do ''not'' force anything and do ''not'' cause cause yourself pain.

===Should the foreskin retract automatically when the penis becomes erect?===
===Should the foreskin retract automatically when the penis becomes erect?===
The answer to this question depends on the relative length of the [[foreskin]] in relation to the length of the [[penis]]. If the foreskin is shorter than the erect penis, then it will retract automatically on [[erection]]. On the other hand, if the foreskin is longer than the erect penis, then automatic retraction will not occur. This condition is not viewed as a problem.
It appears that many sex education classes provide incorrect information about automatic foreskin retraction. Not all foreskins retract automatically when [[erection]] occurs.

A very few of the longest foreskins will not stay retracted when manually retracted. Instead, they will spontaneously [[gliding action| glide]] forward when released. This harmless condition is believed to be very rare.

Many men think a longer foreskin or [[acroposthion]] is better than a shorter foreskin for both functional and esthetic reasons.
[[Longer foreskin is favored]] by many men for both functional and esthetic reasons.
