>>3089203> The "human anus" article has an image of a human female's anus and perineum that probably were damaged by some kind of major trauma. Biological human females should lack an obvious perineal raphe (seamlike union/ridge) in the anogenital region between the anus and the vagina, because the bulbospongiosus muscle is separated in them; embryologically it does not promote formation of a persistent, externally-visible midline raphe as it may in biological males [References: Anatomy & Trauma]. Furthermore, the "perineal raphe" article suggests otherwise (involving urogenital folds) with no support from any cited source.
Aside from relevant material included in Anatomy & Trauma, here is more:
"COMPARISON BETWEEN MALES AND FEMALES
“Erectile genital tissues in both males and females arise from the same embryological structures and thus are homologous” (Yang et al., 2006). The external genitalia of males and females develop from the urogenital sinus (which is divided into pelvic and phallic parts), from the genital tubercle or phallus, from the urogenital folds, and from the labioscrotal swellings. The corpora cavernosa of the clitoris and the glans are formed from the phallus. The vestibule of the vagina, the labia minora, the vestibular bulbs, and the female corpus spongiosum are formed by the pelvic and phallic part of the urogenital sinus and from the urogenital folds (Testut and Latarjet, 1972; Chiarugi and Bucciante, 1975; Standring, 2008; Puppo, 2011a). The phallic portion of the urogenital sinus remains open, and the genital folds do not fuse, and details of clitoral anatomy can be visualized with ultrasound and MRI prenatally (Wünsch and Schober, 2007)."
… "The main difference between the male and the female is the absence of the development of the external urethra in the female (to be precise, only the urethra in the glans is missing) due to the nonfusion of the urogenital folds; however, the structures that form the external urethra in the male are present in the female and correspond to the vestibule of the vagina and the internal surface of the labia minora (Testut and Latarjet, 1972; Standring, 2008; Puppo, 2011a)."
