Pick someone who inspires you. If she has a similar temperament, body type or style to yours, all the better. But remember that there is as much diversity in one's personal sex appeal style as in any other personality trait. Use this person as your guide, but don't try to be an exact replica. If you like, choose different qualities from a few people to create the sexually appealing person you want to be and act like.

Here is another exercise to try this week to help build your sexual confidence. Close your eyes and think back to your early days as a child and remember what it was like before authority figures censored your expression. Think of a moment when you felt peaceful and safe to be everything you wanted to be. If you are a spiritual person, think of how God or the creative power of the universe would want you to fully express yourself sexually. Make that image your goal.
