Something I have always instinctively known, confirmed:

“The vast majority of teachers who harass or abuse their students are men. Men make up just 15 percent of all teachers, yet are responsible for two-thirds of all abuse.”

Via Salon.

The stories of teacher/students sex - usually between an attractive, 20-something woman and a teenage boy - are designed to appeal to prurient interest, leaving you to think that there is an epidemic of women teachers having sex with students. Nope. The ones doing this are men. That has always been the case.
