Why don't girls have peenes?

Girls typically do not have penises because they are biologically classified as female, which is characterized by the presence of female reproductive anatomy, including ovaries and a vagina. This differentiation occurs during fetal development due to genetic and hormonal influences. Biological sex is determined by chromosomes, with females generally having two X chromosomes (XX), while males have one X and one Y chromosome (XY). Gender identity and expression, however, can be more complex and do not always align with biological sex.
