This isn't porn. This is barely scandalous enough to be a freshman dorm room poster.

Meet the  Warwick Women's Rowing team from the University of Warwick in England. In addition to being a very well-respected rowing program, both the men's and women's teams are known for their annual nude calendars, which raise money for Macmillan Cancer Support. 

The calendars are, as you would expect, very popular (in fact, they put them out more than annually, releasing supplementals with their training trips). Most importantly, they're tasteful, and they're for charity—two qualities that we've decided, as a culture, can elevate the "nude" above the "nudie."
