The only laughable aspect here may be the notion of 19-year-olds resisting biology's siren call. The joys of human sex evolved with us to perpetuate the species. I imagine others this week will speak of sex as a delightful gift from a creator.
Either way, let's think late adolescence here: newly out on their own, in a fun college atmosphere (yes, even with an honor code — I went to a church school myself), emotions running high, excited/worried about their team's chances, maybe even in a first love, all accompanied by liberal doses of hormones.
Doesn't BYU's honor code also include provisions for repentance and redemption, short of dismissal, to deal with the inevitable breaches of the code? Or is rule-breaking more typically ignored and this came to light only because Davies is in the spotlight?
