if refering to biological sex i'd use what women have rather than what women don't. e.g. xx sex chromosome
also fun anatomy fact: not all human need a penis to be a human, not all male need a penis to be a male, but clealy someone thinks of penis as such an important thing that he must emphasize it for those who don't have one, don't need one, and don't care for one.
