Why you want it: If he says you’re not having enough sex…you can politely whip out your phone and say “au contraire” with one flash of your app. The calendar on this app will not only discretely allow you to keep track of how often you’ve gotten lovin', but you can stipulate what kind of relations you had (i.e. Heart = Sex; Lips – Kissing/Making out; “O” = Oral sex; “M” = Multiple partners). If anything, this app should help encourage a more active sex life -- the stats, averages and calculations you input create your sexual ranking so if you’re missing sack sessions for sleep, your mojo average drops. No one wants to be told they’re a sexual underachiever, right? You can also calculate how much sex you’ve had during the last three months by entering dates in the “Calculator.” Punch in your stats and see how you rank.
