A condition where the penile [[foreskin]] cannot be fully retracted from the head of the [[penis]]. The term may also refer to [[clitoris|clitoral]] phimosis, whereby the [[clitoral hood]] cannot be retracted, limiting exposure of the glans clitoridis.

In pre-adolescence, the foreskin is adhered to the glans penis, gradually separating before adulthood, leading to a similar depiction for pre- and pubescent characters.

For tagging purposes, this is applicable when the prepuce is not depicted as fully retracted during an [[erection|erec]][[erect_clitoris|tion]].
