With the adoption of Sabermetrics, baseball GMs have elevated statistical analysis over the folksy wisdom of old men named "Sparky". If it worked for the Red Sox, why not for your sex life? MyBlackbook.
From a NY-based web design co., Book's an intricate, cross-referenced ledger that tracks every sordid detail of your sex life, ensuring a disturbingly coherent Remembrance of Things Ass. Simply profile up, then create an "entry" for each partner, providing details both basic (name/age/sex/numerical hotness) and unlikely (phone #); next, record specifics, including everything from date/time, to protection-used/threesome-had, to positions (butterfly, missionary, etc), to "activity", e.g., role play, bondage, watersports, and...kissing? Book will then generate reports for each partner (total sessions with, protected vs. unprotected, etc) plus overall trend charts like Monthly Sexual Activity, Sexual Activity by Weekday/Hour, Session Activity and Session Positions -- confirming the sneaking suspicion that 60% of the time, you're dry-humping all the time.
So your gaudy statistics don't go to your head, Book'll also calculate the probability that you'll contract an STD, and compare that % to the site's and national averages -- which're probably higher, if only because the average person is busier having sex than meticulously recording it.
