Aye Eliza. I used to take a newspaper with me though to get sone rest back in the days of two toddlers, two dogs and her lot always coming over for a cuppa. Rest room indeed in those days. I called it the library.

Pussy is used less, presumably since the double entendres of Mrs Slocombe?

On related titillating humour (note the U) a fanny is not quite our definition, geographically speaking. There was an American music hall song a friend used to sing along the lines of "Everybody wants to hold my fanny, everybody wants to caress my fanny but if anybody was to kiss my fanny! Well, my fanny belongs to me!" In The US, a man could sing it and be funny, takes a feminine touch over here....
