you can because what kid could be arsed to read the bible?
no kid would ever put in the effort to read Song of Songs (or Ezekiel for that matter) because of the associations with boring old christianity (or judaism, since those books are from the Kethuvim and Neviim, collections of scriptures that were adopted (and adapted, controversially) by christianity, once it got its arse in gear. Still, if you read the letter to the Hebrews (in the new testament) you'll see plenty of reasons why all that Jewish stuff actually means something totally different, so that includes all the smutty bits too.
The real christian book is the new testament, you won't find any smutty bits in there, though the Revelation of John (a very important book for most christian denominations/cults) is arguably an incredible account of a psychoactive experience, and i think Saul of Tarsus' miraculous experience on the road to Damascus in the book of Acts could be explained as a hallucinatory experience brought on by sunstroke/dehydration as well. If you look into it a bit more, the sacred texts of the christians really seem to advocate depriving yourself of the basic essentials in order to increase your chances of having a close encounter with the divine.
That's a much more interesting religion than the one about fear and opression that the Catholic church (and many others) has put together over the centuries.
