This MIGHT be the most important thing you hear about Valentine's Day this year. A new survey of women has figured out exactly how much you need to spend on them this Valentine's Day to GET LAID.

--If you're SINGLE and go on a date on Valentine's Day, it'll cost you an average of $257. That covers dinner, drinks, or whatever you do before the woman you're with feels like you've "EARNED" Valentine's Day sex.

--If you're MARRIED, expect to spend about $203, mostly in gifts, to make sure Valentine's Day ends with sex and not, "I really want to but I'm so tired, let's do it this weekend, okay?"

--And finally, if you're in a RELATIONSHIP but not married, good news. You just need to spend $180 on dinner and a gift. Then you can head back for some "we're not bored with each other's bodies yet" sex.
