LA Has the Most Sex ... but Not the Best Actresses are also probably faking it By Tim Karan, Newser Staff Posted Jun 17, 2011 4:15 PM CDT Updated Jun 19, 2011 10:12 AM CDT 7 comments Comments Los Angeles residents report having the most sex in the country, but not the best. (Shutterstock) (Newser) – It's quantity over quality when it comes to sex in Los Angeles. Angelenos have the most sex in the country, but when it comes to fulfillment, they had a more middling 75% mark, according to the Trojan US Sex Census. Philadelphia reported the highest sexual satisfaction (82%), but was tenth on the frequency scale (99 times a year), reports the Los Angeles Times. Trojan interviewed 1,000 adults for the survey and found that the average American has sex 120 times per year. LA residents say they do it 135 times and also reported the highest level of sexual adventurousness. However, Angelenos are also the most likely to fake an orgasm. Those in the South are most likely to abstain from sex until marriage, while San Franciscans are least likely to wait.
