Why haven't I had a boyfriend yet?

[Galelan Of The Atani]

Hi, I know this seems like a really dumb question but I've been thinking a lot about it lately.
So I'm 15 and a freshman in high school. I know that is young (ish) but basically everyone I know is in a relationship but me. I've never ever ever been in a relationship even as a little kid. I've just never had that with someone. It kind of sucks because my friend was telling me, "Oh you're definitely going to have a boyfriend this year!!" and it hasn't happened. It probably never will.

I'm a good student. I'm taking an AP class, an honors class, and German. I'm not like a straight A student. My GPA is like a 3.4. So I think I'm alright in that department. I wouldn't really consider myself dumb, I'm pretty sarcastic and my dad told me my humor is deadpan. Sometimes people can't tell if I'm joking or not... but most of the time I make people laugh. I'm really into history and world travel. My plan is to study world history in college, specializing in Medieval/Renaissance history and religion. So I mean, I have ambitions.

I don't do drugs or drink or anything. I mean yeah, that doesn't really interest me at all at this time in my life. Mostly because I'd be scared of getting caught, aha. I think one thing that people think is weird about me is that I'm really into Lord of the Rings (basically anything Tolkien). I'm like really really into it. I have not met one person who likes LOTR at my school. It's kinda ridiculous. But I like all kinds of shows.

Um, I mean I don't think I'm like hideous like Medusa but I know that I'm not very pretty either. I see girls all the time get compliments on facebook but the only think anyone has ever called me is cute. But I don't really think so. You can sorta see in my profile picture on here, but like yeah I have blonde hair (dyed) and bangs and braces. But I don't wear makeup much except concealer and mascara and I fill in my eyebrows a bit. But that's like it. I don't really dress up either, I own literally 10-12 Lord of the Rings/the Hobbit/Star Trek/Star Wars/Dr. Who/Sherlock t-shirts that I wear regularly and jeans and since it's cold usually a jacket/sweatshirt. So that's pretty plain (but I love my shirts so much). I'm also not like super skinny either but I'm not a hippo. I'm like right in the middle. I am really self conscious of my chin though, it's what I hate most about myself. I wear shorts in PE and I'm not really THAT self conscious about it... (maybe I should be aha).

So yeah, what exactly am I doing wrong? I just think having a boyfriend would be pretty nice but I feel like I'm never going to get one. I feel like there aren't any people like me at my school. What mistake am I making?
