The rise of smartphones with great cameras is one of many modern innovations that only reinforced an enduring fact of human existence: We’re all horny. Heck, innovation itself is horny—for a long time, the prevailing wisdom dictated that new tech would succeed as soon as someone figured out how to make it sexy. It’s no wonder the devices we use for sending work emails or keeping up with relatives are also used to indulge our basest desires.
Sexting is a cultural constant now, or so it seems.
