Always good to see where our contemporary lines of decency/obscenity are being drawn...apparently a snuggie or a blanket with sleeves when combined with sex acts is not passing the censors. Although a parody, apparently Apple believes there are too many kama sutra type apps at this time. While the app is currently not available, all of the snuggie sex positions are still easily accessible on the creators, Lex Friedman and Megan Morrison's, website: http://thesnuggiesutra.com/, which can link you to a purchase of the book.
