It might seem unlikely that men would fake an orgasm. Maybe even impossible. But a surprising 34 percent of men admitted to faking an orgasm at least once in a joint study by Askmen.com and TresSugar.

In the 2012 Great Male survey, 49 000 men from the USA, Canada, Australia and Britain were asked 46 questions based on lifestyle, dating and sex, such as "would you dump a girlfriend if she became fat?" (54 percent said yes) and "would you tell a white lie to avoid an argument?" (63 percent agreed).

Of the 34 percent that admitted to having faked an orgasm, 18 percent said they have pretended to climax on more than one occasion while 16 percent said they've only ever faked it once.

The main reason men gave for pretending was to spare their partner's feelings.

Satisfaction in the bedroom was also a little shaky with 41 percent saying that they were "somewhat satisfied" but still thought there was room for improvement. Only 16 percent said they were completely satisfied with their sex life.

Unsurprisingly, a resounding 92 percent of men in the study said they do care whether or not their partner orgasms and 54 percent believe they can tell if a woman is faking it.
