College student questioning a perspective

I go to a mid size college in the south (about 20,000 students) and I am not sure if I have an accurate perception of the gay community. Maybe you guys can offer your opinion? I am a sophomore about to be a junior and I came out to most of my friends at the end of freshmen year. They are all straight but were completely cool with it. I quickly found myself on tinder and grindr because I wasn't out enough to have contact with the gay community at large. I think this is where I started to mess up my perspective. After a having a few good in the picture guys, I started becoming really concerned with each persons opinion of me. I though that with the gay community being so small, if one thinks that I am crazy then he will tell someone and it will spread like wildfire. I am told I am a pretty attractive guy (I literally have to fight away girls) and I tend to get with the "popular gays" but relations are usually cut short due to the hookup culture mindset present at our school. I think I have an irrational fear that the guys that I get with think I am crazy and I really don't know why. They are usually all assholes and don't care about anything except sex so they, by default, are not inclined to talk to me as much as I would like. I'm not a clinger but I do like to be with guys knowing something about them rather than just hooking up with a stranger. Am I just a nice guy in an arena with sharks or am I just crazy lol?
