Turns out sexting isn’t just for teenagers anymore. In a recent Harris Interactive poll, one in five parents admitted to exchanging racy messages with each other on their smartphones. And a full 30% of parents with kids under 18 admit to sending and/or receiving explicit photos on their smartphones.

Given how it easy it could be to have this naughty material exposed (i.e. losing your phone, or worse; your kid discovers your tantalizing texts when flipping through your phone), it’s a good idea to make sure your personal info stays private.

Lookout Mobile Security, a mobile security company in San Francisco that commissioned the study, offers advice on keeping your information safe. Top tips include turning off text-messaging pop-ups and also setting a strong pass code—in this case, not your child’s birth date. Or download a free security app, such as Lookout Mobile Security, which can not only help you locate your missing phone (and remotely lock it), but also wipe clean your photos and contacts in case your phone lands in the wrong place—like your kids’ hands.

Okay, fess up, workmoms: Are you sexting?
