Athletes at Beijing's Winter Paralympics are not just breaking down sports barriers on the slopes and ice -- Argentinian skier Enrique Plantey is pushing for a bedroom revolution. The 39-year-old and his non-disabled Spanish girlfriend Triana Serfaty have published a practical guidebook called "Sexistimos" -- a nod to the Spanish term for "we exist" -- about disability and sex. They hope it sparks an open conversation on what is a difficult topic for many. "People are afraid to talk openly about it," Plantey, who is a paraplegic, told AFP.
