Trying to avoid anything that may offend Eric Gandma.
The question that all of as parents have to ask ourselves is where is that imaginary line drawn? This type of dilema enters into every decision we are forced to make as parents from when we allow a child to play D&D to the current topic.
Ultimately this is a decision best reserved for the parents - personally, I feel that while 12 years old may not be to young for the discussion (how I am NOT looking forward to that talk - my kids are 4 and 2 respectively) on sex, it is to young to be experimenting - certainly with supposedly benign toys.
Granted certain adolescents are ready for something like this, but I would prefer my children to keep thier innocence as long as possible.
So while you point TrizzlWizzl is certainly valid, I can absoletly see - and respect the need to procted children from something like this.
