Interesting. I don't claim to be an expert on ancient Egypt, but it appears from those 2 pics women had bush (pubic hair) & the men were shaved?
It would be helpful to know the reasons. Health problems?
W/o modern things: *INTERNET*, widespread porn, widespread photos & publishing, etc W/o all those modern things, shaving down there would be less popular. (& less well known)
Pretty sure Egyptians didn't have any of those things, but they DID have cast system, many only certain people?
Also, not very clear exactly what they're doing. Circumcision, & various ornamentation was/were also practiced back then. Sexual ritual? Probably need an Egyptian expert to explain all the "bones?"
