Hahaha, I apologize that it seemed I came off as threatening and defensive, just a little bit of a gun nerd and couldn’t resist defending my sweet S&W .40 (and I now have a sudden urge to cap on the AK, lol).
But back to the topic (with all seriousness). I’ve known a couple girls like you, and my suggestion along with the others that have answered, is be who you are, don’t change just for the sake of trying to attract boys, it’s really not worth the effort. They’ll eventually pop up, as I said, within the next three years probably, and from what I’ve seen with the girls I’ve known that seem similar to you from what I understand from your question, it’ll probably be either male friend you may have currently or another guy that you know who has similar tastes as you.
And as you made clear to me, you are a fourteen year old girl, having only one boyfriend so far is not something to be ashamed about at all (then again, despite me being 19 right now, the thought of anyone under the age of 15 being in a boyfriend girlfriend relationship seems little weird/awkward/peculiar to me). Having a few but long relationships shows that you are capable of steady, stable relationships, which is a lot better than having many but short relationships that simply show you’re controlled by your hormones and not the other way around. It’s the quality and not the quantity (as with anything) of relationships that should matter.
