Final answer:
The question does not correspond to a clear concept of 6Fs related to women's bottoms within an academic or health context provided in the reference materials. It is possibly associated with broader topics about women's health and societal views on women's bodies.
Step-by-step explanation:
The question 'Which of the 6Fs only pertains to women's bottoms?' does not directly pertain to a clear set of 6Fs within a recognized academic or health context, as provided in the reference materials. Therefore, it is not possible to provide a definitive answer. However, considering the relevance of the provided excerpts, it appears the question may be indirectly related to discussions about women's health, specifically issues such as reproductive health challenges like obstetric fistula or cultural perspectives on women's bodies as seen in historical or anthropological contexts. The excerpts provided touch upon various topics including the portrayal of women in ancient literature, the legal considerations of sex as a Bona Fide Occupational Qualification (BFOQ) in employment, and the importance of maintaining genital health without the use of special feminine hygiene products.
