After all it is futile to try and change long-held male attitude such as "after forty women are sexually obsolete." If love is supposed to be an ageless, timeless thing, than an age difference should not matter particularly if the eyes that you seem to be locking with seem to be those of a soulmate.
The degree to which the teacher-student romance is abhorred depends usually on the age difference between the two.
A primary school teacher who is involved in a sexual relationship with one of her wards will elicit the most outrage and is prosecuted as a criminal.
Students are immature and overwhelmed by their teacher’s personality, they look up to the teacher with admiration; so it is highly immoral to take advantage of these innocent feelings and deepen it to an adult romance.
The main fault in a teacher-student relationship is the lopsided power equations. The student is too immature to make a proper decision for himself/herself.
Other students suspect favoritism and awarding higher grades to the student involved with the teacher.
They may attribute the wrong motives and may see an undesirable nexus between awarding grades and sexual favors. Allowing mentorship to turn into romance breaks the trust on which a healthy student-teacher relationship is founded.You spot an attractive man from across the room and suddenly your eyes meet. Still the part of you that believes in equality is outraged at the double-standard society holds against May/December romances.This locking of eyes lasts for just a few seconds longer than a gaze that just means "hello." He winks at you and offers up a swanky grin. It means, "I'm available." A few moments later he comes over and after you get a closer look you realize, that you are 45 and this is the oldest looking 25 year old male you have ever seen in your life! Surely if HE were the older one in this budding attraction, there would not be any problem at all.This is one kind of relationship that our society frowns upon much the same way it condemns child abuse or paedophilia.A teacher-student relationship is by tradition, considered sacred.What are those bad names that society calls older women that date younger men again? He would just be behaving like Donald Trump, Michael Douglas and a variety of celebrities and politicians who have much younger wives.
