Perhaps the most successful in a long line of attempts to justify and explain Twilight:
Because Edward Cullen is porn. Weird, pre-sexual, socially conservative, deeply repressed and fucked-up porn, but in a world where ladies’ sexy feelings are fenced in with shame and warnings of danger from Day 1, is it any wonder that porn which consistently ties sex to death and fear and the urgent need for repression is selling to the girls?
