When an attractive young girl returned from her honeymoon she was in a state bordering on desperation, and decided to write to the ''Aunt Marge'' page of her weekly magazine:''I am at wit's end since it seems that the nice boy I married is really a sex-maniac. He never leaves me alone -- he makes love to me all night without stopping, and then while I'm cooking breakfast, cleaning the house, while I'm in the bath, while I'm watching TV, and so on, he just never stops! Can you please tell me what to do? Signed, Exhausted in Peoria P.S. Please excuse the jerky handwriting.''
