The British Heart Foundation polled couples in Great Britain and found that nearly 20 percent can go for an entire week without kissing.
When couples do kiss, 40 percent only hold the smooch for five seconds or less.
Things get better as you get older, though. Five percent of couples over 45 say they make time for kissing.
The study also found married couples ages 18 to 24 kiss an average of 11 times a week.
