If I might ask, why the double standard? If a male teacher sleeps with a student, he's a pedophile, monster, or pervert. When a woman does it, it's treated as a joke and the response is generally "Where were these teachers when I was in high school?", and people just generally gauge the teacher on hotness and decide if she was worthing banging.
Now, this isn't the kind of story that enrages me, even if it was a male teacher (for the most part, I consider a 17 year old able to make their own decisions) but I just wanted to point out the double standard. In both cases, it's an experienced adult taking advantage of a child, in the eyes of the law.
