Which would you rather give up for a weekend — sex or your iPhone? 15% of respondents to one study said they would choose a romance-free weekend rather than go without their beloved device. A recent survey conducted by Gazelle.com (the company that buys your old iPhone) asked 1,000 people who have used the service to trade-in an old device if they’d rather go without sex or iPhone for a weekend. Yes, 15% of people chose sex.

This isn’t the first time smartphone owners admitted they would give up sex over their smartphone. In a related survey by another company, smartphones tied with intimate relationships as two things business professionals said they couldn’t live without. But there’s another relationship between iPhones and people’s sex lives — nearly 4% of respondents to the Gazelle survey reported having used their iPhones while having sex.
