Why don't guys like me?

Hi, Ok so I have this problem; guys just don’t seem to like me, they always ignore me and when I do talk to them(or atleast try to) they look at me like I had just told them that I had webbed feet or something and I don’t know why. I have long black hair, caramel skin, dark brown-almost black eyes, I’m 5’4 and I’m not skinny but I’m not morbidly obese either.I’m average sized I guess.I play the violin(I love music) and I get good grades.I’m a bit shy when I meet people,but when I know that I can trust them,then I pretty outgoing and my friends say I have a good sense of humor. Sooo I don’t know what’s wrong with me, it’s not like I have hygenic problems or anything. And sometimes it’s not just guys but other people too,it’s like I’m not good enough to talk to them. What should I do??? Any advice? Please give your most HONEST opinion please!
