A little child's world is dominated by feelings. He cannot usually reason that a concept of himself as homosexual (because someone forced an unnatural stimulation upon him) is false.
Quite so. Often the nicest, kindest, coolest older man a young boy has ever met is a chickenhawk boy seducer who "courts" him all the way to sex, in very pleasurable surroundings etc.
How can a 13 year old deal with that, and develop a healthy heterosexual sexual identity? Even if he does not "go gay" for at least a while, he will be screwed up six ways from Sunday.
Castration for chickenhawks would be a good start. Kneecapping and blinding might be appropriate also.
