Oh, the dreaded "crush on straight(?) guy friend" thread is back.

Oh, I can just hear the moans and groans of yet another "crush on a straight guy" post. Many apologies.
I haven't come out to a single person yet, so this is rather awkward to type to total strangers. Thanks for bearing with me. I'm a freshman in high school and a total band geek. I'm also bi (I think, sexually attracted to men, emotionally attracted to both men and women). I've had two girlfriends, and this would be my second crush on a guy. For our purposes, let's call him Joe.
He is in my section and we sit next to each other every day (both second altos). We've only known each other since August, both we've really gotten to know each other and are best friends. Recently, we went on an out-of-state band trip and that's when this all really began. Our hotel room was him, two others, and myself. For whatever reason, Joe thought it'd be a good idea to play truth or dare. I was already starting to get "those" feelings for him, as on the several hour bus ride there, we really bonded. At one point, he even fell asleep on my shoulder. I would have enjoyed it more if our band director wasn't sitting directly behind us O.O. Whatever position he was in, I always "accidentally" shifted poisitions to a point where we were somehow touching. Oops. So, anyways, back to truth or dare. Joe was recently dumped by his girlfriend, so we did a lot of "guy" stuff. In that game, Joe and I had hugged, layed on each other, and other less-than-masculine things I can't remember at this point. Afterwards, we slept in the same bed (no complains there). We positioned ourselves somewhat close to each other, and facing each other. It was bliss.
Prior to that, when Richard (another changed name. Fun, isn't it?) left the room to talk to our band director, we scurreyed in the bathroom and I put my shirt on backwards and he took his pants off (hawt) and put them on backwards to make obvious implications. We then proceeded to hide in the closet. When he returned, we pretended to make out. One of the dares was to lay on each other (no idea why, put a pillow inbetween us so he wouldn't feel...you know...) and afterwards (in bed) he said "it's only gay if you think it's gay".

The next day, at the amusement park, we esentially pretended to be a gay couple for a while. We held hands several times for the weird stares us band kids know all too well. On when on the rides, just out of the blue, he grabbed by hand and we held hands. Totally private. I'm sure there's other things I'm missing, but that's the jist of it.

On the bus ride home, he once again fell asleep on my shoulder. It couldn't have been on accident, or comfortable, as I was shivering (soaked from a water ride, and dry clothes were buried under the bus). He slept there for a majority of the time, until some of our friends started laughing at him. Fear not, I'll beat them up later. Not really. I'm kinda sarcastic, if you haven't already noticed.

So what I'm really getting at...I just can't tell what's going on. Like, I know a lot (if not all) had the goal of making people feel awkward (it's just what we do...) but somethings I felt like he really enjoyed. Like, through several of these activities, it appeared as though he had a boner (sorry, younger crowd). And the holding hand things. So many mixed signals. I can't tell if he's just really comfortable with me, or if he feels the same why I do about him. It also came up on our too-loud (laughter was heard loudly, and our room had to be inspected for girls, lmao) game of truth or dare that the farthest Joe would *currently* go with another guy is hold hands. And then he held hands with me the next day on the ride. I just, don't know what to make of all of this. If that was totally intentional and supposed to be a major hint, or just a coincidence. I'm having much difficulty masking these feelings and not making them totally obvious, so any advice on the matter would be much appreciated. What I'm ultimately afraid of is telling him I feel, being rejected, and awesome friendship goes down the drain. Also, one of our section members (and soon to become section leader) who we are REALLY tight with is slightly homophobic. One of the seniors (bi) is trying to inform her. But if he were to reject me, and think I was creepy or something, we would find great difficulty working together. (For those of you who don't know, band [especially marching band] require great amounts of collaboration) And what we have would stop. I'm really looking forward on the trip next year (much longer) for this same experience. I seriously can't tell if he's straight and being friendly and all that, or is bi/gay and giving me signals. Help.
