when I was at the U of London in the 70s, one of our colleges was very close to Soho, it was more convenient to go into the coffee shops in Soho than back to the main building at Bond Street. Sorry, for those who don't know London, Soho is the red light district. One of the favoured entrances by the working girls was, 'keep a girl?' the answer was, 'I'm a student, I can't afford to keep myself' everything was fun and we often would buy each other coffee, gangs of students and gangs of working girls together. One of the things they'd say was. 'long and thin goes too far in, short and thick, does the trick,' It seems that whilst a woman's anatomy is designed to carry a baby and give birth, it is not designed to accept anywhere near that size to put the baby there.
