I see that 19 wasn't mentioned; I must have got it from that other thread.

However: "...a young female 'clubber' decided that me or my neighbour were to be a source of amusement" implies someone old enough to probably be over 13 years of age, let's say. At least, far beyond the age of paedephilia.

Maybe because I grew up with four brothers as well as four sisters, I don't have much of a male-female divide in my head. I have heard people object to 'unisex' restrooms and I don't understand it- in your own home, don't both sexes use your bathroom? I've been told that in public restrooms women leave much bigger messes than men do (with good reason, I understand- Women utilize items that men don't.)
