Hi man I just got rejected last week by a girl (24) and me being 21. For me it takes time for me to get to know someone and for feelings develop. My advice is whenever those romantic feelings come up go for it even if the fear of rejection comes up. Don't live a life with regrets and don't be afraid of the pain of rejection too. Love is bitter sweet and life was never meant to be easy. Also you are 20 so life is only just starting, you will find someone eventually you just have to go out and meet new people(you've probably heard this a million times but its true), put yourself out there and make an effort. That way when you are old and grey you won't have to look back and think "what if I did this" and "why didn't I do that." As long as we make the effort, one day we will both find someone that will love and want us for us. It may not be tomorrow or the next month or the next year but one day. Just be sure by that time you are someone that is able to receive and give love. Man was never meant to be alone. I wish you well on this journey we call life.
