One-in-3 U.S. women fantasize about a sexual rendezvous on the Eiffel Tower, while men prefer the White House, a survey found. The survey, conducted by Harris Interactive among a total of 29,003 U.S. adults for condom maker Durex, found 46 percent of respondents said they were more likely to see Big Foot than climax at the same time as their partner. Half of Americans said they felt dissatisfied with the duration of their bedroom escapades -- 37 percent of respondents admitted the time they spend being intimate ends too quickly, while 14 percent revealed that sex lasts longer than they would like. This dissatisfaction has led to 75 percent of men and 66 percent of women trying to change the pace while making love, the survey indicated. \"This gap in satisfaction is something that has been occurring forever,\" Kevin Harshaw, marketing director of personal care at Reckitt Benckiser, parent company of Durex, said in a statement. The survey was conducted Sept. 6 to Oct. 3. No margin of error was provided.
