Dear Jessica - he will grow up anyway and the sooner you accept it the better for both of you. For better learning results your boy needs a passion, a desire to know more and believe what he learns is good for him. The belt nor any cage is not the way. There is nothing wrong with occasional masturbation, a relief can help him concentrate and rid of abundant arousal ,althougn some level of chastity can help him keep his energy. Yes, too much masturbation is harmful, bot no relief is bad too. Balance is the key. And if your ever considered hormone blockers - forget it, this would be even more dangerous and harmful solution. Even when he grows up, he will always be your little boy. Just treat him with love, respect and care and accept him as he is. Just be his guide and guardian angel. Things he needs most to learn is your wisdom, patience, will, love and trust, because there is nothing wrong with puberty. Do you have a husband, Jessica?
