Interesting debate. As I'm less familiar with the US academic system regulations not including my academic visits to my colleagues in US universities including some ivy ones. To be honest, my knowledge about fraternities and sororities is very limited.
Let me add my personal view on the matter. Many years ago (I am way over 50), I was an instructor (a PhD student), my students were a few years below me and above 18 (I was is my early twenties). I was engaged in long term sexual relationship with one female students (we were a couple for one year). Her friends who knew about it didn't make a fuss as it was quite normal (I wasn't a faculty member) and the age gap was negligible. She broke up with me as she felt that we got apart of each other. She was quite right and we ended up as friends with no negative emotions. About a year later (I was about 2/3 of my PhD studies), I was teaching a student that was ten leagues above me in terms of sexiness' and beauty (She looked like Camila from Being a DIK with Sage's breasts). Don't ask my why, but we hooked up. It was a summer fling. The sex was incredible and she was very adventurous. We went to a park, sat on the bench, and without warning, gave me a BJ, we had anal sex (This was my first time). She ended our relationship as she thought that she needed to find herself. Well, I was devastated for a while. Less of romantic feelings and more because I've became addicted to sex with her.
Years flew by, I met my wife (she looks like Maia from Being a DIK - Well she looked liked her 25 years ago minus three children). I became a university professor. To be honest, I below average on looks, my social skills are subpar. However, when I'm teaching a class, I am perceived as highly charming and charismatic (beyond class, none of it is true. I'm a regular person).
Did female students ogled me. Yes, because I'm the charming professor during lectures. Did I acted upon it, of course NOT!
Never had, never will for three reasons: 1st: Morally, I am happily married. I will not destroy my family for an affair. 2nd: In today's climate (since the 2000's, you have to be mad to get involved with a female student as you might be at risk of being accused of sexual harassment). 3rd: This is the highway to lose your job. No thank you. I worked hard to get to my position, I will not throw it away for some sexual urges.
I taught some gorgeous and sexy female students over the years. At most, I fantasized and masturbated while thinking of them. Still, it remained only a fantasy.
The code of conduct is very strict in every university that I've been in the US, UK, Canada, Australia, New Zealand and Israel.
Is that mean that there are no professor-students relationship, of course not. There are probably some that I'm not aware of. However, when it explodes, that's the end of a career or being charged with sexual harassment charges. In both ways, you lose. In today's academic climate, I'm telling my PhD student to be very careful not find themselves in a tights position. I told them, female students in our department are like candles, you only admire them and looking at them. Female students from other faculties, colleges are ok to date as long as there is no risk of potential coercion.
So, for me, Being a DIK is a fantasy story of student's life that I never had a chance to experience. during my undergraduate studies years, I had a girlfriend.
That's my two cents and my perspective on this debate.
And a final anecdote to give a glance to who I am.
My flirting skills with women are those of Ebola virus. Most of my romantic relationships started as I was approached by women. To give you an example showing my lack of social skills. I was 18 years old at high-school. A gorgeous 17 years old from my high school invited me to her house for a date (She told her parents to go out and planned a romantic evening). She looked like Sage from being a DIK but with blonde hair and green eyes. We were lying on the carpet listening to music. She approached me. I did nothing. I froze. Was I stupid, yes! I didn't know how to react. Well, If I was the MC in Being a DIK, the result was different. The sad truth, I really offended her by my behavior. At that time, I didn't see that as my social skills were much worse and my understanding of the female specie was non existent.
