Did you know that just by walking down the street, or across the office, people may be able to figure out that you've gotten láid?

Because having a 5aginal 0rgásm does more than just put a little pep in your step. It actually causes you to walk differently, with a longer stride and a greater pélvic rotation.

In a European study, trained s3xologists were able to pick out, with an 81 percent accuracy, which women had an 0rgásm just by watching them walk.

But that's not the only way someone can tell if a woman has had s3x. Here are a few others:

The Glow: There's a scientific reason for us getting the flushéd in the cheeks look after s3x -- more blood flow -- but what about that aura of calm that seems to float around us after the fact? It happens. Recently, my husband and I went on a post-coital grocery store trip and ran in to some friends. The wife remarked to me, "You're glowing," with a little wink and a nod.

The Cat Who Ate The Canary Grin: This is also known as the Smirking Smile and if you see a woman looking sideways with this look on her face, you'll know, yep, she just got láid. She has a secret that's making her go through her day with a sense of fulfillment. Because, seriously, nobody is that happy unless they just had s3x with a happy ending.
