Secret Sex Signals

First impressions happen fast, and often below our radar.

It takes only 90 seconds to 4 minutes for someone to decide if he or she is attracted to us or not.

And since it happens so fast, you may not have any idea you've ignited lusty feelings in the person silently observing you from across the room.

What triggers these quick takes? Research shows that 55 percent of the time we are able to hook someone because of our body language; 38 percent of the time it's the tone, speed and inflection of our voice; and a measly 7 percent of the time it's from what we say.

What's this mean? Basically, that someone has decided if they like you or not before you even open your mouth.
