Thou shalt mind your privacy settings
Repeat after me: password protection. If you lose your phone and don’t have a passcode, that homeless man who finds it on the subway platform is in for a real surprise. Also, turn off your iMessage previews. Random pictures are all-things-yes, but when you’re at mom’s house and an unsolicited pic of Mike’s crown jewels pops up on your home screen, have fun making awkward dinner convo.
Thou shalt delete all evidence
You should really delete a racy pic from your phone immediately -- sent or received. But if you live life on the edge, just don’t let your friends or grandmother scroll through your pictures. And always, always, ALWAYS keep the first photo on your camera roll PG. If you have a few hall-of-famer photos you want to hang on to, store them in Private Photo Vault, an app that requires a password for viewing. For the rest of you, take a long, hard look (lol) at your photos of nether-region naughty bits, then delete all traces from your texts, camera roll, and "Recently Deleted" folder. Or, just don’t send a photo of your penis at all. Because, newsflash: women generally don’t find them hot.
Thou shalt recycle wisely
Capturing the perfect shot takes 20 minutes and a great hair day. Since sexting is often initiated when one party is bored and seeking immediate validation, recycling your favorite photo is bound to happen. But screenshot the pic first, then send that version to sidestep the 2012 timestamp.
Thou shalt avoid being blackmailed -- and stupidity
You can never be sure you won’t get blackmailed, so there must be an established level of trust between you and your sexting partner. Significant others are more respectful of your privacy because they want you all to themselves. But if you cheat? Your naked fanny could be projected on the wall at his next party. I’ve seen it happen. Booty calls should be approached with extra caution. How well do you know him? Do you have any of his incriminating photos that could scare him out of exploiting yours? Unless there’s a strong probability of you two dating, risqué snapshots serve as bragging fodder at wing night. If this prospect concerns you, don’t press send.
