Do I need to change something about myself?

Henlo subreddit I just have to write this out. It probably does me more good to put thoughts out there then anything else so bear with me. I know this may touch on several common experiences in LGBT community so any advice you have is helpful.I'm a 19 year old college student (sophomore). I've known I've been completely and entirely gay for about 4 years and I don't really have a problem with it. I have not really "come out", but I don't necessarily hide the fact; I tell my friends I am gay if the issue comes up.However I have noticed as I become more comfortable with being 'publicly' gay I am becoming more insecure with my appearance. I spend so much time thinking about how I look and what I can do to improve my desirability. In fact, my (girl) best friend from high school says I've gotten much more attractive in the last few years. I have been going to the gym for over a year as I used to be very skinny; I take assiduous care of my skin and wear BB cream, I make sure my hair looks good before I go anywhere, I have good style, and I think I exude an air of confidence though she says I seem aloof at times. Regardless I find myself very average looking.I think most of this insecurity derives from the fact I've never done anything romantic or sexual with someone. I don't really know how to go about it either. I go to college at a very small school in a very small town. While it's very liberal and there are plenty of gays around I am attracted to almost no one. Even to those I am I have no idea how to approach them. There is one boy I have a crush on who is the most handsome one in the world. His sexuality is very unclear to me but I just wish I had the confidence to talk to him. He was in one of my classes and has talked to me on occasion but I'm just so damn quiet and aloof around him, even if he did like me I'd be in the same place.I downloaded Tinder and made an OkCupid account a few days ago while I'm on break in my home city. On Tinder I've swiped right on roughly 12 people in my city and got like 3 matches. I've been chatting with one person for a while but I don't know what to do next.Overall there is a big conflict between my loneliness and high standards. Anyone I feel remotely attracted to has the face of a model, and of course is very kind and intelligent. It has made me want to get plastic surgery so I can look more like those I like and make it easier for me to find a relationship with one of them, because average looking people have to work harder for the same thing. I am scared of being condemned to a certain lifestyle because of the angles of my face. Though I feel like my desire to have a relationship with someone very attractive is just a projection of my own insecurity and a means to validate myself. I am sorry if it this all sounds very shallow but I assure you I do not consciously judge people's character based on their appearance. Anyway, I guess my questions for you are: am I better off just trying to wait until I graduate college and move to a larger city to make this more feasible? Does getting therapy work to reduce insecurity and thus lower my standards? Any other ideas?Thank you for reading !
