It is hard to read some of these opinions/comments. If a 15 yr. old girl is texting her 42 yr. old teacher and he responds inappropriately to her then the blame lands squarely on the teacher. Why?. The child does not understand or comprehend enough of life simply because she is a child. There is a lack of maturity not only of the child, but the teacher is immature. This is why the Lord puts the children under the authority of the parents. Some of you are to immature to get this. All sexual deviancy comes from a lack of properly understanding sexual intimacy in God's design of marriage. This rebellion is given rise to the present day sexual chaos. For those of you who think that consensual sex between a 15 yr. old girl and 42 yr. old man is just fine, you need to grow up. This man does not know how to relate to a mature women. All the perversions of homo sex, pornography, feminism, child/adult sex,, effeminate behavior, what ever it is that rebels against the Lord's design in real marriage is evil. The agenda is to undermine the authority of parents so they can sodomize the minds and bodies of children. 
Woe unto you, scribes and Pharisees, hypocrites! for ye compass sea and land to make one proselyte, and when he is made, ye make him twofold more the child of hell than yourselves. Mat.23:15 
Being filled with all unrighteousness, fornication, wickedness, covetousness, maliciousness; full of envy, murder, debate, deceit, malignity; whisperers, Backbiters, haters of God, despiteful, proud, boasters, inventors of evil things, disobedient to parents, Without understanding, covenantbreakers, without natural affection, implacable, unmerciful: Who knowing the judgment of God, that they which commit such things are worthy of death, not only do the same, but have pleasure in them that do them. Rom.1:29-32                                                                           His servant, Peter
