If you need a way to keep track of how often you get laid and make sure you know which day of the week it is, this heart calendar from Brigada Creativa pretty much has you covered. Each day has a heart on it, and you can fill the heart in (full heart for sex, half heart for messing around, etc) or not as you so choose. And at the end of the month, you’re left with both art and a reminder of who that baby’s daddy might be.
