I want to fall in love?

I'm so lonely and I've never really felt a strong connection to another man. I guess that's partially because I keep people at arms length, I'm an emotionally closed off person and I am prone to being shy depending on the situation. I get sick of being like this, and I try to put myself out there (even though if I feel like I'm too-overbearing my friends ure me that I'm not, and I always end up getting hurt.) I'm smart and I think I'm attractive and when you get to know me I can be funny. I'm 19, never fell in love, never really done anything with a guy (if you count drunken gropes and sloppy kisses at college parties), never been in a relationship and never had that many guy friends. I'm so lonely and I want to fall so deeply in love with another person. I want to experience it so badly, and I can't help but think that maybe I should just let it be, and that it's not meant for me. I'm just so lonely, I have friends and family but none of them know that I feel like this. Nobody truly knows the extent of lonely I feel everyday. Well expect you guys, what should I do?
