To add to the current discussion, I think if anything we ought to be less prudish about sex in media. You can get away with some pretty nasty gore in films, but show ‘too much sex’ and it’s an instant blacklist, which makes no sense to me.
Obviously 80s ‘PG’ is a far cry from PG films nowadays, but Raiders of the Lost Ark had a dude’s face melt off and then explode, but too much swearing or basically any explicit sexual content is an instant NC-17.
