While accenting a great figure can't always hurt, don't neglect showing off who you are on the inside. Talk about things that you have in common and don't veer off into a self-inflated monologue about one of your obscure hobbies. Though it is important to tell a new love interest all about yourself, let your story unfold naturally, with lots of give and take in the conversation. Don't talk about past lovers. Body positioning should be 'open and inviting'.
Light touches are a very sensual way to test the waters of attraction.
Another little trick to put a new date at ease is to fiddle with your hands, twirl a pencil or straw or play with your napkin or drinking glass. This shows nerves and puts your date at ease. Make your romantics intentions clear, but don't forget to be sensitive to signals for the go-ahead.
