I think it is a great advantage for you to have possibility to date someone from your living and studying area. I gave up Tinder and Match.com as soon as I moved to Des Moines and got an opportunity to meet people from my town (I used https://kovla.com/datings/us/des-moines ). Big sites have millions users with a lot of scammers and weird people, with no perspective for real relationships. As for the professor - I don't know how I would act in his place, it's great risk to lose job, even if you're from different college...From the other side, do you need a man who isn't ready to take a risk?)
