Every Monday here at Daily Intel, we publish a sex diary. But this coming Monday is special: It’s Valentine’s Day, the day of love and romance (also sadness and masturbation). To honor that occasion, we are going to try something new: Everyone is invited to do a one-day sex diary for Monday, February 14. Make a note of every time you have sex, think about sex, simulate sex, or even reject sex from the moment you wake up to the moment you go to sleep. Then on Tuesday morning before noon, send your day’s diary to sexdiaries[at]nymag.com. Since we’ll be dealing with a bunch of diaries and won’t have time to check them out the way we do with the regular diaries, this will be on the honor system. But we trust you guys! For some reason! Also please note: Unlike our usual sex diaries, this is not limited to those of you in the New York region. So Californians! Canadians! Our one reader Mat Mat from Kuala Lumpur! Now’s your chance to allow us to peep behind your closed doors…
