A typical sexual encounter lasts about a half hour, according to new results from the Great American Sex Survey.

The Great American Sex Survey, by Adam & Eve, indicates 15% have sex once or twice a month, while 7% say they have sex every few months. However, 3% say they have sex daily, and another 3% say they have sex only once or twice a year.
