I feel for all men who have been falsely accused of sexual misconduct. My suggestion to all men who are entering a academic field which may require contact with students is the following. Every time a student touches you on the elbow, or anywhere else, tell them not to touch the merchandise. Do this from the first day you give a lecture and stay consistent. Do this to both male and female students. If a student continues to do this, make a scene in from of the class and tell them that you do not wish to harassed, academically or sexually and that if it keeps happening that you will take the appropriate action. You will probably to laughed at, but you will build up a reputation of non-physicality if anyone, male or female, comes after you in your future.
