X Chromosome

The X chromosome is a sex chromosome, also called a gonosome. Together with the Y chromosome, it is part of the chromosomes involved in biological sex development. In simplified terms, many female organisms have two X chromosomes, while many male organisms have one X and one Y chromosome. In reality, sex development is biologically more complex and cannot be fully explained by this simple classification alone.

In BDSM or sex dictionaries, the term usually has no direct erotic meaning. It is mainly used in a medical or biological context. For a precise explanation, it is useful to distinguish between chromosomal, gonadal, and anatomical sex development, since these traits do not always match exactly.
