LONDON, ENGLAND - JANUARY 08: A billboard poster advertising a nasal spray for male sexual problems is displayed on January 8, 2009 in London, England. The ASA (Advertising Standards Authority) has asked the Advanced Medical Institute, who are promoting the spray with the phrase "want longer lasting sex ?", to remove the adverts. They have refused, even though the ASA has received 400 complaints from the public. (Photo by Peter Macdiarmid/Getty Images)
