Yes, this is certainly true, but I think you have to go further downstream, before the paraphilias start to emerge. Though we should be thinking how we minimise the escalation of these things. Making them socially unacceptable is good, but I think individuals affected also need personal strategiies.
But what triggers this kind of sexual response in the first place? I think that it is happening more often, not just that it is allowed to escalate. We know it can happen young, when sexuality is first emergent, maybe even earlier in sexualised environments. It's not a situation such young people affected are creating, it's something they are being exposed to. We should try and minimise these kinds of triggers in our culture.
And adolescents are not taught to think that some sexual thoughts can be unhealthy or dangerous, or that it might be a good idea to control them, or how they might do that. Quite the opposite actually, they are taught that they are not dangerous, it is dangerous to suppress them, and they won't be successful in doing so anyway. All after creating a society riddled with sexualised content in everyday life.
So these kids, when ther are first aware of these feelings or urges, before anyone else is aware, are working from a position of, all sexual urges are ok if you aren't hurting other people, and they are even a part of "who you are" and need to be honoured. And they don't yet have the insight or experience to question that at a time when they might be most likely to be able to do something about it. Because years down the road when it's very established it will be much harder to do anything about it.
