Its an old saying but it was a true one about the American solders in WW2 their over sexed and over here and as an Island cut off and relying on food and supplies from abroad its hardly surprising that young females offered their services for stockings food and other luxuries and its not much different today is it its done for money and its called prostitution.
Reminds me of a story my late nan told me. At the age of about 17-18 in the 20s my nan and her friend were took by their ears( the good old days) back to their respective parents cos the bobby thought they were soliciting.
They were just talking to each other on the corner of the street!!
