Why are Teachers having sex with students

Why are teachers having sex with students does anyone know. It has been going on for years, even centuries. At one point in time it was male teachers having sex with female students, now female teachers are pushing the envelope and having sex with male students and in some cases even having homosexual relationships. What is so unsettling is the fact that these women are willing to throw there lives away, and go to jail. Then say that it was all done in the name of love. Why? What fixation could cause such mental instability to think that they can continue to have sex with these young men and keep their job? Reality check, did this teacher not know she could go to jail? Holly Hatcher, was a High School teacher in Gallatin, Tennessee, before she was charged with 3 counts of statutory rape, because she had sex with one of her students. The ultimate shock is that these relationship are becoming more apparent with female teacher and a young male student to most people. I think that the penalty that women should suffer should be a stiffer. Simply because if it was a man, they would want to lock up up an throw the key sway!
