Trust the filthy minds of cellphone developers to turn innocent text messaging into depraved sex messaging.  NTT DoCoMo in Japan will soon be selling a handset that, once instructed with the menstrual details of its owner (presumably female), will sound an alert three days before ovulation and then again on the day itself.

Other functions include a “recipe database” and “camouflage melody” button, the latter of which causes the phone to fake-call you should you be attempting to avoid the advances of a family-hungry man who has seen your fertile-light flashing.
