Is Student Teacher Sex OK??? What about if the Student is at least 18?

[stormiestl]

This is a poll... I want your opinions. A law in Texas makes it a felony if a teacher has sex with a student regardless of age. So that means high school or college students can not have sex with their teachers or professors. A 25 year old female teacher is on trial for having sex with an 18 year old male student. She can get 25 years in prison for it. Is it right? Is it wrong? why?
