Sexting refers to sending sexually explicit messages or photos digitally. Studies show that between 7-20% of teens ages 14-17 have engaged in sexting, with higher rates for older age groups. Parents can install monitoring software on devices to prevent sexting. Schools debate cell phone policies, with options including a ban, only allowing use during passing periods, or no restrictions. One school implemented a cell phone jammer to block signals but the legality of that approach is unclear.
