A wife made a splash posting on reddit, complaining about her husband e-mailing her a spreadsheet detailing the ways in which she had declined sex over the previous 7 weeks. They are apparently a 26 year old couple without kids. He had apparently tried to initiate sex 27 times in that 7 week period and was successful on 3 occasions. She gave some pretty standard excuses during that time: tired, feel gross, have to get up early tomorrow, wanna watch TV.
Any of those excuses alone look perfectly reasonable, but when they start to amount to a 90% rejection rate start to look like bullshit. So, the husband responded in a hugely counterproductive and passive aggressive way. He not only made a spreadsheet, but he sent it to her via email as she was headed off on a 10 day business trip. That last rejection may have pushed him over the edge - wanting to watch TV instead of having sex before she left on a long trip. So, that last one isn't just a one day rejection -- she was essentially turning him down for sex for the next 11 days combined because she didn't want to miss her shows. But that spreadsheet email maneuver is pretty much guaranteed to make her vagina clang shut.

Disclosure: In the past, I kept a diary of my wife & I's sex life to see just how infrequent things were and make sure I wasn't going crazy about just how rare the sex was and the reasons for the infrequency. But, at the end of the day, it doesn't necessarily matter - if you're getting a lot of "I'm tireds" it might mean she's tired, it might not. But it definitely means she's not attracted enough. And, if your wife isn't attracted to you, you aren't going to logic her into wanting to have sex with you - no matter how solid your data is.
