Closeted gay problems. Got advice? I don't know if I should pursue him, or just stay in the closet corner I call home.

Alright, so I want to start this by saying that this is not a question or a situation where I'm seeking help to muster up the courage to come out.I'm 20, gay and secretly proud of it. The problem is, I live in the middle-east. Now, I know what you're thinking.. "Ooh that's a tough place to live for an LGBT person" and I completely agree. However, that doesn't mean that there are no gays or some sort of secret LGBT community. We have all the gay hookup apps, a lot of TV and Social personalities appear to be openly gay but have never verbally admitted it. Yet, everyone kinda knows.I also grew up as a Muslim. I still consider myself to be a Muslim, while I do not practice it perfectly; I still believe in the religion. Now, just like Christianity and Judaism, it goes against being gay. So, I have grown up knowing it was wrong, way before I have come to terms with my sexuality in my teenage years. Therefore, I kept it to myself, with time I have accepted the fact that.. yes, I'll never have a relationship with a man, or a husband or a family a truly want. I'll just have to find myself a woman to marry to keep the eyes from starring at me and my social status. This kills, but I'm not going into it as it really depresses me and makes me truly sad.I also can't go behind everyone's back and join or have relations with another person, not because I'm afraid of my society and family but rather the religious seed that's been planted in my head when I was a child. I still to this day, think that my religion would accept me seeing as I truly never really found attraction to women, I've always for reasons my young mind couldn't comprehend at that time, liked men. However, just thinking about being with someone of the same sex scares me.If you've made it this far, thank you! I realize this must be boring as you've probably heard it many and many times before.Anyways, I currently live alone as I'm attending university. Which I thought would liberate me from all the problems mentioned above, unfortunately I thought wrong.A few days ago, I was on one of those gay hookup apps. I never really get anything out of it, meaning I don't hookup or go on dates, I just chat with people online and become envious of their carelessness and courage. My profile was very basic and had no pictures of me nor did it have any detailsl; pretty much anonymous. As I was looking at the people near me, I found a profile of a man that had a super attractive picture, as most of them do. However, the name was interesting. It said "Nationality Expat" (Not middle-eastern). I couldn't believe what I read, seeing as that the previous day, we had a new professor from that same nationality (Not middle-eastern). Obviously, I was like "This is him. Oh. My. God. This is him". I mean why wouldn't it be?! Same nationality, his arrival coincided with this new profile that popped up. Same body type, beard. I was very excited, I didn't know why. Anyways, this man was wearing a watch in the picture, so I made a mental note to check my professors wrist and see if it's the same watch.Next morning (today), I had him on my first lecture. I sat down, and waited patiently - I know, creepy. I should get a life right? So he walks in... Same god-damn watch. What was interesting is that throughout the lecture which had about 50+ students present, we've been making eye-contact. I kept thinking it was all in my head, but I swear it was true.Level of excitement: 100x10.Lecture was over and the day progressed with one long lecture after another followed by one long lab session after another. Towards the end of the day, I felt like I needed to speak to him, I wasn't planning on saying anything specific or special. I just wanted some sort of verbal exchange between us. Just to see if my "Gaydar" picks up anything.I went to his office, knocked on the door and entered. I smiled and greeted him, he did the same, and I asked him some stupid question about lab instruments."Hey Dr., so for our lab, do we need any specific instruments and tools like the other subjects?""Oh. Instruments." His eyes dart at his desk. "Maybe get a model of a skull" He says that with a clear smirk as if he's joking. (I'm in med. school by the way.)"Haha. Wait, really?""Why? You don't know where to get one? Haha, don't worry. Just bring your lab coat.".. I figured the language barrier made it a little hard for me to find 'the funny'."Alright, ok. Thank you doctor." As I was opening the door, with one foot out ready to leave. He asks me very swiftly."How old are you?" "20." "Ohhh. Really? Haha ooh you look too young" He said, very very friendly, which border-lined flirtatious.I awkwardly smiled and exited. I know. So stupid of me to do! I wish I could go back and like say something to... I don't know, something. My flirt game or whatever is really bad.My Gaydar spiked! I am now, 100 percent positive that this man is gay. This made me happy for some reason, it made me feel... less lonely? I don't know. I could be reading too much into the exchange that we had, however, I'm very confident that the profile might be his!As I was driving home I kept thinking, and I realized that I should probably talk to him on the app. I did that (By that I mean said "Hey! How are you?"), however, he's offline on the app all of a sudden which disheartened me. I don't really want to be in a relationship with this man, he's my professor, that's unethical and I know that. Despite him being incredibly hot. But for some odd reason which I can't understand, I just feel the need to let him know on this app, that I'm gay. I don't know why. I feel like if I tell him that, and if he knows it, I'll be liberated in a sense. Liberated from the shackles that my society and religion locked me in. I feel like it would make me feel less alone. I've never had a friend that knew I was gay. I'd be someone else outside my living quarters and someone completely different inside it. That's why, for some reason, I feel like if he knew I'm gay and I knew he's gay it would make us both share a secret that we're not allowed to tell to different people. Seeing as he's also from a place that's not gay friendly by any means.So, does anyone advise me against it?
