This isn't what you meant to say at all. Please don't use words that you don't know the meaning if, in order to impress or look mre inelligent than you are. You only make yourself look far worse, than you already have managed to do.
Since the topic of this thread, is talking about children, who are 12 and a little more; your anecdotal example of an 11 ear old ( and in some places, 11 year olds ARE in middle school ! ) , that does fall into the ballpark.
Is it your contention, then, that 17 year olds are " mature " enough to engage in all manner of sexual acts ?
