Well, that'll teach those girls that S-E-X is evil and bad and scary and they should give up any plans they have for using those naughty parts "down there" until they're safely married and even then it should be lights off, door locked, under the covers, missionary position ONLY and of course only if they're doing it to make a baby.
What I wanna know is, are they showing the boys the same film?
I dunno, RR--we got shown that old-time classic, "I Am Joe's Heart" or something in 6th grade, and for the 3.2 seconds that they showed an actual, wet, live, beating heart, eveybody in the class but me screamed "GROSS!" and covered their eyes. You never know what's going to affect kids and in what way. On the other hand, it sounds like the particular movie they're showing should be reviewed, perhaps by some representative parents, before being shown again.
Nobody goes into nursing thinking, "Oh boy! Can't wait for the puking and spitting and pooping and pee and blood and pus!" We all have things we deal with better than other things. The point is, when you get to the point where you're dealing with that stuff, you realize there's an actual live patient behind it, and the icky stuff is just an unpleasant but inevitable by-product of their illness.
