On average, the Durex Sexual Wellbeing Global Survey found, Americans have sex just 85 times a year -- about once every 4.3 days -- well below the global pace of 103 times or about once every 3.5 days. They also spend an average of about 57 minutes per week having sex -- about 14 minutes below the global average, the survey learned.

When U.S. adults are in the bedroom, 69 percent said they had oral sex, 62 percent said they had sensual massage and 42 percent said they enjoyed sexual fantasies, the survey found.

More than 50 percent of U.S. adults expect that lovers will become more experimental in the future and 57 percent look forward to people being sexually active for longer in the years to come, the survey said.

Condom manufacturer Durex questioned more than 26,000 people across 26 countries about every aspect of their sex lives.
