the boys do not need that much having healthy relationships with people who support and care about them. Okay, they obviously and blatantly do need it, but that's precisely why they shouldn't get it.

Hee! (Are - are we bad people?)

Well, if you're having trouble with the Christianity-and-homosexuality thing, I suppose you could write Castiel as a technically genderless being (or just think of newbie1990, who's a Christian but has no problem with homosexuality at all). If I end up writing anything about the ethics of possession-sex, it's probably going to be the fic in which Sam wants to have sex with Ruby but can't get around the consent issues.
