When an adult has sex with underage kids there is no difference in eyes of the law or shouldn't be. Just out of curiosity how young does a boy have to be before an adult female having sex with them warrents serve prison time?
Nature does not observe any form of calendar. Nature dictates that a male or a female ceases to be a child when he or she reaches sexual maturity, i.e., having the ability and the impetus to reproduce. According to Nature,
that is the difference between children and adults.
That stage of development is called
puberty. Some children reach this critical stage sooner than others and are classified as
pubescent (girls menstruate, boys ejaculate). Adults who engage in sexual activity with
pre-pubescent girls or boys are called pedophiles. These are predatory perverts, sexual deviants whose actions are not only against the laws of civilized humans but also violate the laws of Nature.
The reasons why so much hell is raised about "under-age" but pubescent females having sex is they can become pregnant and they are subject to victimization by more physically or socially powerful lecherous males. In fact the need to protect young females from lecherous males dates back to prehistoric times.
Modern socialization and its attending puritanical complications have resulted in laws of Man which ignore and expediently supersede the laws of Nature. But in spite of these socialized laws there exists no such substantive need to protect boys from women as there is need to protect girls from men. These laws simply deny the essential nature of the male, which is his impetus to screw anything with a warm, slippery hole -- including his teacher!
Nature made him that way -- for a very good reason.
