There's a fine line between joking and hinting - But where is it?

First of all, an introduction. I'm 14 years old (yes, young, I know.) and recently coming to terms with the fact that I'm actually gay, and attracted to men more than physically, as it has been before. As far as I can tell, I seem pretty normal, I'm not overly flamboyant or anything. Then again, I've heard of people coming out and their friends say they knew, so what do I know? I hope you will hear me and my questions out, as well as give any advice you can.Where to start, where to start? Well first of all, I moved to where I am currently living at age 3. No, this isn't gonna be a life story, don't worry. One of my mom's friends had a son the same age as me. We weren't friends as kids, but we became friends, and we're getting to be better friends recently. We don't see each other too much, despite living across a highway from each other. Im in scouts with him, so I see him every Thursday as well as a week for summer camp, when we're always at each other's sides. He also comes with me to my Grandmother's house for a week at the end of the summer. Does that sound worse than it should? My Grandmother actually isn't all that elderly, and she has 380ish acres in the mountains with atvs, utvs, etc. Its really fun up there, and we both enjoy it. But most importantly, it gives me a ton of time alone with him, which is where this story starts and the title begins to be relative.He's definitely more outgoing than any of my other friends. Recently, he's been almost hinting at not-exactly-straight-ness. However, you know how kids our age are. He could be joking for all I know, and I'm wasting my time on wishful thinking. He's definitely more in with the crowd more likely to do that, and I am not. He doesn't seem like he's making fun of anything, as others in our grade do, annoyingly enough. I could be going insane and imagining all of this on the hope that he is gay/bi, but I'm not sure. He always seems like he's trying to get closer than anyone else would, but that's not too prevalent. Occasionally, when he goes to the bathroom/shower, he'll jokingly mutter something like "Wanna come with?" Even though I heard perfectly clearly, I'll say "what?" He'll respond with "nothing!" Unless he's more clueless than I thought (and he's not the sharpest spoon in the knife drawer), we've come up with our own way to comment on that, which he'll kinda give into, but not really. He also has some things that other kids our age would not have, to the point of his younger sister accusing him of taking something of hers. It was his. Last but not least that I can think of, we have slept in the same room/tent several times, and that's where the last thing starts. I sleep fully-clothed, he sleeps in just boxers, which is perfectly normal. I completely forget how it got to this, but he ended up telling me "I don't care, you can sleep like this," referring to himself and in almost a requesting way. Again, I may have imagined that, because I'm not the most attractive thing... But I have always slept clothed and he knows that, so I'm not sure. All these and more over the past 2ish years have led me to believe that there's something that he hasn't told me but kinda wants to. Am I completely insane? As of now, I plan to kinda add some hints of my own, and wait for it to progress further. What is your advice for me both on this issue and in general? I apologize for any typos/formatting, it was 2:30 am when I wrote this, and I was on mobile.I appreciate any tips you can give, and let me know if this belongs anywhere else.Thanks!
