There is a time and place for everything in this old world and cellphone use during sex is not one of them. That being said, almost ten percent of all Americans admit to using their phones while engaged in sexual activity.

There's a time to be connected and a time to unplug, but those lines are blurring for many Americans addicted to their smartphones. In fact, according to a new study, about 9% of people have used their mobile device during sex, from checking text messages to answering phone calls.

The 2013 Mobile Consumer Habits study reveals some fascinating habits of smartphone users, including that three in four Americans (72%) are within five feet of their device most of the time.

Although similar studies crop up about once a year, the latest results indicate many are not curbing their habits.

"It's no wonder people in relationships feel like their phones are cramping their love life — 12% of respondents in a relationship said they believe their smart phone gets in the way of that relationship," the study noted.

Other surprising places people are using smartphones include at church or a place of worship (19%), on a dinner date (33%) and in the shower (12%). About 55% of survey participants admitted to texting while driving.
