Casual sex should be with somebody you actually like. My new rule of thumb is to only shag men I don't mind sleeping over, and am okay with kissing goodbye when they leave. Anyone else isn't worth my time- and if I'm not prepared to make at least that much effort, I'm probably not worth theirs, either.
In short, those who enter into the glittering halls of Hollywood through Disney are destined to suffer a gruelling initiation into adulthood, through whichever duct of filth reveals itself first. Some of them get a taste for it, and are doomed to an existence of public arrests and nervous breakdowns (we're looking at you, Brit). For others, reincarnation is possible.
