[NSFW] Advice on an issue. Please help.

Okay. So in advance I apologize for length. If you make it to the end, thank you!First, some background information. I am 15 and gay (duh). I know that's young, but dont hit me with that. I have had 2 crushes before. One was on a girl (before i realized i was gay) but it was still a crush. I got the heart is fluttery and the so smart, so cute, so perfect and such. The whole shebang. It was really advanced and it became a bit of a low key obsession. I got over it and started to realize my gayness. That was in 8th grade. I went crushless freshman year and for the most of the first semester of sophomore year. Then i developed a mini crush on a guy, started to develop it, the whole fluttery thing again, admiring him from a distance. Then he mentioned his girlfriend and that ended that crush SUPER quickly.Now, on to my issue. In the last couple of weeks, i've started to develop, well, feelings for a guy. That's what my post is about. Help me figure those feelings out. So we've been friends for about a year. He's nice. He's funny. He's smart. The turning point for me came a month ago when we were studying together for finals. We walked to a Starbucks together and had some coffee. We chatted for a bit. I really enjoyed my time with him, conversation seemed easy and we just clicked. I started to notice that all the time i spend near him, im happy. Many of my friends find ways to stress me out and stuff, but he just doesn't. But here's where it gets confusing. In the past, with my crushes, I've wanted to basically have sex with them. Its been more of an infatuation. They're always in my head, always filling my thoughts. This guy tho isn't. I don't have a total longing to have sex with him. I just lay in my bed and pretend to cuddle, or spoon. I want to spend time with him, just chat and hang out. i want to cuddle. I dont find him HOT (As in want to bone) but hes not bad looking. Hes almost kind of cute. And dont get me wrong. I would have sex with him.Thats the information part. Now's the analysis. The way I see it, there are 3 categories. Friend, Infatuation/Crush, Love. I've heard people say that love is different than a crush or an infatuation. That its more real, that you'll know it when you see it. This feels different from what I've experienced before. What do you think it is? What would you call it? I don't know if he's gay. I don't know if hes interested. Which brings me to my second question. I really love our friendship. I don't want to endanger that or ruin it. Therefore, I cannot act. My question is, Would coming out to him (im not out) and confessing my feelings strain our relationship if hes straight/not interested or make it awkward in anyway? And therefore, should I do that?Thank you for reading and making it this far. If you have any questions or need clarifying information, please ask
