Jess is the main reason I still have hope for the youth these days....
OP, you're 13 and you act younger than that. Stop being selfish, there I said it. You're being completely selfish with what you WANT and not even considering what a bearded dragon NEEDS, which in this case are two polar opposites.
Fact: bearded dragons are solitary animals and territorial
Fact: when two males are confronted, they will fight to the death for the territory
Fact: when multiple bearded dragons are housed together, dominance is established (arm waving, head bobbing, stacking ontop of one another competing for more light--it's not them hugging and being cute)
Fact: when multiple bearded dragons are housed together, fighting WILL occur
Fact: you will not be watching them EVERY minute of the day to pull them apart if they start fighting (when you sleep, when you're at school, when you're out with family/friends)
You're denying all these facts that SCIENTIST have dedicated their lives to study. You know, they do publish this information in books.
You're 13 but now you have a life to take care of that's not your own so you can't think like a 13 year old with that life. Do what all responsible mature adults do and research proper care of bearded dragons from scientist, vets, etc. Germ, Jess, Tastiger, all the mods/admins here, soo many other members here all know this information we are trying to give you from experience. They've experienced all the heart break and witnessed enough from dragons being housed together, it's best to listen to them.
Best of luck to your dragons, I hope you make the right decision for them and not you.
