We'll be talking about body language soon, but this is one level up from that. Have you noticed that when you're near each other, your lover just can't keep her hands off you? If you're sitting together at a restaurant, she has to be holding your hand or touching your leg. If you're on the couch at home, she can't resist cuddling up to you and kissing you.
We don't think we need to explain what happens when the two of you find yourselves in bed together. Physical touch is a great indicator that your partner is crazy for you. If you want to be as close to her as she does to you it's a match made in heaven. Just remember not to make too many family members and friends uncomfortable with your constant contact!
