For completely unrelated reasons, I also like this bit in a book I'm reading for the first time, Arthur C. Clarke's The City and the Stars, about revamped humans a billion years from now:
In the appropriate circumstances, there was no doubt about the masculinity of any male in Diaspar. It was merely that his equipment was now more neatly packaged when not required; internal stowage had vastly improved upon Nature's original inelegant and indeed downright hazardous arrangements.
