Should I cut it?

I'm a 15 year old male with slightly wavy, dark blonde hair; about 3-4" past my shoulders. I have a light complexion, and a long, narrow face. I've had long hair for about 5 years now, and I've been considering getting it cut. If I do, it will be first thing in the morning (it's 1:30 AM), and I don't if or how I should get it cut. I've heard a lot of girls like that spiked/gelled look; but I think it looks a little preppy. I dress like a skater--baggy pants and that kind of thing. I dunno what to do, so if anyone could give me some advice, that would really make my day...

hey well i'm 15 too, except i'm a girl. i wasn't going to respond but long hair is nasty(don't take that offencive)sk8r guys are the only guys, and ur gonna feel much better after u get it cut.ur posted e-mal says ur getting it done soon and so i asume it's already cut. the spiky look isn't preppy, but the pushed look is. so believe me no matter how it's cut as long as it's short it look better!
