having a crush with your own lecturer/teacher?

so just wondering if you people out there have ever had crushes on your professor/teacher/lecturer? so will this crush be more of a disadvantage or an advantage to you? as for me, i feel that it can be both but you need to make use of the feeling you have towards your teacher to benefit yourself. so, on the positive side, if you ever do have a crush on your teacher, it can somehow motivate you to study and do well especially for his module as you will want him to have a good impression on you..yeah.you wouldn't want your crush to think that you are stupid or an idiot rite. on the other side, having a crush or your teacher can also be something bad if you cannot control your feelings. so lets say the teacher is teaching the class and you keep looking at his cute face without paying attention. looking at your teacher somewhat makes you lose focus and you keep staring at him blindly. im sure that a lot of students out there have ever had crushes on your teacher/lecturer but have you ever wondered if lecturers ever had crushes on students???yeah something to ponder.
