It worries me that I am not at all sure how to write the analogue of this list from the perspective of a devout mormon without something along the lines of "premarital sex is bad because I despise all that is good and joyful in life, bwahaha"

I mean, I think it might have something to do with the solidity of families, but there's still some steps I'm not seeing (ie fully sex-positive families in scandinavia seem to do just fine)
