Mindie, 36, received unwelcome questions and comments regarding her relationship and sex life with Sean Stephenson, 35 who was born with Osteogenesis Imperfecta, or Brittle Bone Disorder. At 35, he is just 33.6 inches tall with shorter than average legs because it affects bone growth.

She responded publicly and revealed that they have a great sex-life.
