This is a body positive campaign, no doubt about it," Kuba says. "To be loved is to be known, and to be known is to be open, and you have to show yourself which is incredibly hard to do if you feel things." This isn't the first time the Danish babe has stripped down for fans this month. Earlier in April, Nina posted another sexy photo of her posing nude in the woods. "When the light and your boyfriend are cute, you gotta do what you gotta do,” she captioned the photo, which raked in over 105,000 likes.

A year ago, San Francisco photographer Anastasia Kuba decided to switch her artistic direction. The former dancer had been a boudoir photographer since 2008, but she was ready for something different. "The pictures that came out were really gorgeous, but they turned my stomach upside down because something was deeply wrong about them," Kuba tells SELF. What was wrong: Kuba felt the images didn't capture the real person in front of the camera.
