A little lost navigating the gay world

So I am a 24 year old gay guy who is partnered, engaged actually to another man, in Florida and I feel lost because I don't have any gay or straight friends as I relocated here with my fiance a few years ago from another state. By nature I am shy and in high school I was able to meet friends because of constant contact in classes etc but meeting friends in adult life has been highly challenging for me. Because I am shy I do not automatically come out to others as gay although I consider myself out. What ends up happening is there have been people in college classes that I felt maybe I clicked with as far as friends but didn't pursue the friendship because I wasn't sure if they would be accepting or reject me if I came out to them. I feel like its the biggest lie to "come out" because you don't just come out once or twice its a daily thing and for people like me its aggravating and makes me resent myself sometimes for not being more self confident. So for a while I was hoping maybe some people on grindr or scruff would also be looking for friendships and how wrong I was. I did meet a few people on these apps (not hooking up) but it never worked as far as friendship. So now I just have given up and am not really bothering to meet anyone at the moment. I know there are gay groups out there at schools and churches etc but it seems so artificial and forced. It seems sad to me that even a year after marriage has been legalized for us most gay guys are soley focused on sex first and foremost. Guys like me who are already partnered with another guy are like fish out of water. I feel so frustrated someone please give me some advice.
