What is wrong with me?

I'm being honest here, your really cute.
I think it's more that guys your age are really shy that most are too intimidated to make a move (no there's not much you can do yourself as it's the guys' problem).

I think that it's tough to tell what the problem is in your situation without knowing more about you or what's going on in your life. I agree with meh-bodo. If confidence is your issue or being shy, I agree that it does truly make you almost invisible to other people. I also went through the same thing. I had to finally find ways to start "coming out of my shell" and finding out who I am in order to be able to start connecting with people. Find something that you enjoy doing and you will gain confidence and start finding out who you are so you can get out and meet people and learn how to be yourself around them. It was really tough for me for a while because I was scared that people wouldn't like me, but I found that the more I did it, the easier it became, and I gradually began to become more confident and bold in myself and who I am and to meet people and found out that they actually like me for who I am, which is cool! Good luck to you! :)

Maybe your into the wrong kind of guys but hey hit me up if your interested because I haven't had a girlfriend either and I know I'm not butt ugly you know so yeah if you want to get to know me better hit me up

Would your friends say you are drop dead gorgeous, I know people are their own worst critic, maybe guys are scared to ask you out because your so hot. another thing to take into consideration is your attitude, do you have many long term friends, do your family get along? you may have picked up some bad social habits. another thing may be confidence, if your overly shy it can make you seem invisible to other people or even make it seem like your too much of a snob to talk to them. you really need to look inside yourself and just self improve where ever possible. go to the library and get out a book called "how to win friends and influence people" by Dale Carnege, its a fantastic read and gives you a great insight into the mentality of other people, I strongly recommend this book.
