This site discusses phimosis in its specific forms of phimotic ring, frenulum breve, adhesions or skinbridges.
During erection these conditions inhibit the relationship between foreskin and glans.

Full circumcision (particularly for infants) is a ridiculous treatment or prevention for any form of phimosis.
Those who follow Abraham are asked to please consider using his methods of partial circumcision.
