When I was in college a gay friend of mine had a problem that sounds similar to yours. He could easily find guys who wanted sex, but no one who seemed willing to see him as anything other than that sort of opportunity. We talked about it, and it turns out he was looking in the wrong places: gay bars, baths, saunas, and so on. I suggested he check out the gay students' organization on campus and that opened up all kinds of opportunities for him. Don't be afraid to call them and say "I'm real nervous about this". They will understand; they've ALL been there.
I am not gay, but I want to comment on your idea of finding "the one" and connecting that to the idea of finding someone who will appreciate you just as YOU. Those two things are different. You are 19, bro. You have a whole LOT of life ahead of you, and I would not be worrying right now about whether or not you will find someone to spend your life with. Finding people who will accept you and care for you just as you are, however, is something else. We all need that, regardless of our sexual orientation, and remember that you don't need to reward friendship with sex. Many survivors, teens and adults, fall into that trap.
You are special and important just as you are, and without any sexual attachments or connections. There are plenty of people out there who will be willing to accept you on that basis - including, to begin with, friends you make here.
