I think many men today have their brains altered from watching too much excessive porn. Fetishes develop and normal healthy relationships become problematic due to performance issues. There are many worse thing than porn, yes, but to be healthy well rounded adult, it does not help (at least excessive). Family can help, but some topics are taboo in many families, especially when man ego is in question. If you could not statisfy your wife, would you speak with your mother for help?
Yes, you can say it should start from young age, but both parents are at work and kids are left with high-speed internet and tablets. They react positively to porn and can get addicted - its a single click away. Hard to prevent that, eh.
I think we will witness the true effect of porn on males mind in future.
