No, a 13-year-old is not capable of handling all the emotional and physical aspects of having sex with an adult. The adult is taking advantage of the youth, and it is considered a form of abuse. Society has rules. A person may marry at 16. While the age of 16 may seem too young for marriage, in the eyes of the law it would then be acceptable. A 13-year-old youth has not even stopped growing yet- he is neither mentally or physically mature to engage in an adult relationship. The adolescent is usually not prepared to deal with the consequences either - say if there should be a child produced by the union. There would be financial burdens and societal pressures too difficult to face.
A 13 year old male child is still a child. Depending on how he was raised, he might be aware of sexual situations, but he would lack the emotional and physical maturity to deal with an adult sexual situation. Years ago, our nation put laws into place to protect our young women by making it illegal for older men to engaged in sexual acts with them. This situation is no exception to that rule. And that rule was put in place because minor children are not capable of handling sexual situations the same as adults. Male or female is regardless in this situation. Had this been a 13 year old girl and an older male teacher, he would have already been UNDER the jail, and the victim would be in counselling for many years to come.
No, a thirteen-year-old is not capable of handling all the emotional and physical aspects of having sex, let alone having it with an adult woman. A thirteen-year-old is barely capable of handling the emotional stress of getting out of bed in the morning or the physical stress of putting on his or who shoes. Clearly, an adult who does this with a child--yes, a thirteen-year-old is a child--has the emotional or mental capabilities either.
Cases such as these in which a female adult violated a male teenager are often viewed with a different bias than if the genders were reversed. If it were a male teacher and female student in this situation, I believe there would be unanimous outrage over his violation of a child of 13. There's no reason why the same logic shouldn't apply just because the student in question is a male. He's still a child at 13, and therefore incapable of engaging in a consensual adult relationship.
