Of course an Aspie can find love. I know many who have romantic partners and many who are married and have children. There really is someone for everyone out there. It just takes some patience to find them.
You are only 20. Contrary to what you see on TV and the movies, it is not at all unusual for someone not to have had a relationship by then. Please relax. You have plenty of time.
Part of your problem is that you are too focused on “getting” a girlfriend. It rarely happens that way. The most stable love relationships are those that evolve naturally out of a friendship. Slow down. Instead of pursuing love, pursue friendships. That means joining some activity where there are both men and women who enjoy the same things you do. Colleges are full of service organizations, clubs, political causes, and activities where people get together to share experiences, develop their talents and find friends who share their interests. When people are focused on staging an event, doing a project, or building a team to accomplish a task, there are lots of opportunities to talk and get to know each other without the pressure of dating. Over time, some of those relationships blossom into romance.
I wish you well.
