It is genuinely repulsive they do that. I knew a fat who claimed to be raped (apparently him going bareback is rape) and piled on the pounds.  Fats read about women who have dealt with regular sexual abuse by doing things to become unappealing. They decide to claim that one of their awkward sexual encounters was rape so no one will question the balooning. Fats ruin everything, including recovery for humans dealing with traumas.
