Types of body language that suggest attraction include smiling, eye contact, uncrossed arms and legs, leaning forward and tilting the head to the side. More subtle forms of body language showing attraction include flushing of the cheeks, pursing lips and directing feet towards the other person.
These body language signs can be broken down into their specific meanings. Eyes flicking down to the mouth and back up to the eyes can indicate sexually attraction. When a person's back is straight and head is up, this typically signifies openness. When someone nods along to another person's words, this may not only indicate she is listening, but also that her movements are paced to your dialogue, suggesting a potential sexual compatibility.
