Is it normal if i'm all for teacher-student relationship?
I don't think that it should be okay between male teacher and female students. I think it should be okay between female teachers and male students because I don't believe anyone is actually hurt, however; I do think its weird that a female teacher would want to have sex with a male student but its her decision. I think the only thing they should do is not allow the female teacher to continue being the teacher of the male student or fire her in violation of policy because that might impede on his current academic performance. From 5th grade all the way to graduation I had crushes/fantasies on various teachers. In locker rooms us boys would definitely let each other know about what was on our mind about certain teachers. Males are wired completely different from females as far as sex goes. If anything, charge the male student as well for perpetuating the relationship and don't put all the blame on the female teacher. 15 year old dudes have raging hormones and ready for anyone that gives them a chance...and banging a teacher would represent lifelong bragging rights.
