Miami - Sex beats riding the space shuttle or being president for a day, but half of all Americans would rather go on a free shopping spree, a survey published yesterday showed. When asked to choose between sex and an unlimited shopping spree on someone else's gold credit card, 57 per cent of American women found the latter option more appealing. British-owned condom manufacturer Durex asked 1,055 US men and women aged over 18 to talk about sexrelated issues as part of a survey of almost 10,000 people in 14 countries.
