Bro. Take it from me, I was in the same boat as you until basically this year. I have long hippie hair, I wear clothes that I like and accessories that I like. I've had one date this year. All I have to say is fuck it, I'm with a girl who thinks my long hair is hot and likes to smoke weed with me. I do what I want, I refuse to conform to the stereotypical nonsense. I've got loads of friends because I'm different and I have respect (the fear kind however) because I'm tall, skinny and a pothead. I don't think you should change. But thats my opinion, I'm not much farther ahead than you. I've been laid once and fooled around alot but my experience is'nt that extensive. Being tall for my age helps though (14, 6'3"-ish) anyway, leave your hair alone damnit. Be yourself.
