Use Your hands
“Women who gesture often are perceived as more likable,” says psychologist Frank Bernieri, who specialises in non-verbal behaviour. His research has found that men are drawn to more animated women.

Speak Up
The key to making him melt isn’t always what he can see. “When a woman’s voice is energetic and varied, it can increase a man’s heart rate and boost testosterone,” says Deborah Blum, author of Sex on the Brain.

Lead with Your Hips
A sexy swagger shows off more than your low riders: “When a woman juts her hips forward slightly, she sends a subliminal invitation to approach,” says Beverly Palmer, an expert in non-verbal communication.

Touch Yourself
To really get him interested, take your hand off his leg and put it on yours. Non-verbal sexual cues – licking your lips, caressing your neck and hair, arching your back – drive a guy crazy because they draw attention to the body parts you enjoy most.

Get Closer
Leaning in is universal body-speak for “Wow, you’re fascinating,” Palmer says. Up the arousal factor by maintaining an open, inviting posture and holding eye contact while smiling and nodding. If he feels interesting, he’ll think you are too.
