Attracted to authority figures

I'm a 23 year old girl and I tend to be attracted to women who are older than me and in a position of authority. It's not something exclusive, I've been attracted to girls my age and it will happen once in a while that I'll fall in love with one. I don't usually "fall" for women who are older, I'm however incredibly sexually attracted to them. Now I'm at college and they're fairly common. In my country it's usual to go to paid colleges, which means there are a lot of older people in class, it's not that "17 year old fresh from highschool" type of class. It's a mixture between single mothers, married fathers, and a bunch of 20 year olds. The thing is, these are NOT the women I'm attracted to! I tend to be attracted to my professors or supervisors (internship class). The "culture" in my college means there really isn't anything separating us from them. They go to barbecues with us, they drink with us, most of them are friendly (and sometimes more, specially male professors) and we even exchange numbers. There are very few of them whom because of their personality are more "closed off". But it's common to hang out and discuss personal issues with them. So you can see how it's easy for attraction to happen. Every since I entered college there's always one female teacher I'm "obsessed" with. It's always the same thing, it starts with admiration and then a few weeks (or days) later I'm fantasizing about them. My teachers, specially women, are between 30-40 years old.

However, I'm fairly bugged by my new attraction. She's 59 years old! She is considered attractive by many. Incredibly funny (we call her class the "stand up class"). Well dressed. Elegant. She's not motherly at all - quite the opposite. She's the "vodka aunt" stereotype, like Lucille Bluth come to life. And just as rude as her, which makes me even more attracted. I put my number on her test, mostly as a joke. It was the last one and we wouldn't have classes with her anymore. No, it wasn't disrespectful - like I said, it's pretty common for friendships and hook ups or at least attempts to here in my college between students and teachers. She's single so I didn't really mind. I've had "crushes" on married teachers and I would never do such a thing or even let them perceive my attraction. And now she stares at me a lot, smiles a lot when I talk to her (which is unusual for her), finds reasons to stand near me and hang out in my class. She knows I'm attracted to her so it's a weird behavior. It's actually scary how much she stares at me sometimes. It's not that "is my crush looking?", it's very predatory and she does it when I'm at a short distance. I even watched her class even though that's forbidden and she should've kicked me out, theoretically. I did it because I have a friend in the third year (I'm in the fourth) and I wanted to hang out with her a bit. All she did was smile and lose her concentration everytime she looked at me. The girl in front of me (the friend) even asked "Why is our teacher looking at you and smiling to herself?" which made me blush a little. But she didn't call nor anything. It looks like she's "considering" but doesn't want to cross that line just yet. And I intend on seeing how far I can get. The moment she stops interacting or says "no" I'll respect her request. But so far she has been friendlier than she was before I hit on her.

And I don't have mommy issues - my relationship with my mother is great! This only makes my attraction towards women three times my age even more curious to me.
