You are beautiful whether or not you know it. The shape of your eyes, nose, lips, and the nuances of your body all define who you are, and it reminds you and your significant others all of your characteristics and help create the image of you that they know and love. You should be proud of what you have and capture a moment in time where you feel your best and can look back and smile at the photos. You should also take this opportunity to feel sexy, to flaunt what you have, and to finally put on that corset or lingerie set you've been meaning to wear.
The biggest risk is never having tried, and the best reward is having one of the most memorable moments in your life.
