What positive images of female sexuality can you think of in popular media?

Women in todays popular medie who I personally feel display an image of positive sexually would have to be women like Michelle Obama, Alicia Keys, and Beyonce. To name the first three that come to mind. They are all constantly subjected to paparazzi in there way and having their daily lives put on display. However, all three uphold a respectable way about themselves. At times they can dress 'sexy' and be very feminine but never cross the line to where they are overly exposing themselves. Beyonce especially whether in performances or videos has a very sexy demenour but always in a respectable womanlly fashion.
