In this day and age where one takes bath at least once a day everyday, where is the concept of a "unhygenic" penis come from?

Understandable that your ancestors lived in places where there was scarcity of water, like middle east, or europe where the water was maybe just too cold to take a bath everyday(not mine...in my society/religion there never has been circumcision for atleast 5000 years)

But in this modern society, I findthis concept of cutting off the skin simply horrendous.

If the skin was not supposed to be there, why did God provide us with one?
