Are the signs right or is my mind playing tricks?

I've posted about this subject before, but I'm not feeling any better and really need good advice. So it's about the usual "I like my best friend" subject. As I've said before, I never fall for straight guys since I've always known that turns into a headache, but this guy is just different.

First I'll talk a little bit about myself. I've had interest in guys since I can remember, but I've never come out to anyone. I'm a senior in college. I'm pretty sure my really close friends suspect I'm into guys, but I've never even kissed a guy before, because of fear of people finding out. I've dated girls and had girlfriends, even long relationships. The thing is I've liked about 2 of my straight best friends before, but ignored it since I always knew they were straight. I've never felt depressed or whatever about it. But with my new friend it's different. Let's say we are both in the 19 to 24 age range.

I met him two years ago. We were varsity teammates. We got along great from the beginning. This is when he was a freshmen and I was a junior. I always thought how it was weird that he wasn't doing good at school, and he didn't have a girlfriend, never went out on dates, he never hanged out much (maybe once a month), and everybody always talked about how he never talked about girls, even to his close friends, so he basically just spent time by himself. Even one day one of his closest friends told me how they went to their high school senior trip and he didn't hook up with ANY girls, and even gay guys get really drunk and hook up with girls in senior trips, right? Anyway, he tends to spend his time smoking up with guy friends. He doesn't even have girl friends, I've NEVER seem him even talking to a girl. Sometimes I think he is just gotten used to this behavior, since he is from a guys only school. So this is all the year I met him, but didn't spend a whole lot of time with him. We hung out like once every two weeks. We were just friends.

This year I got really close to him. We are together almost everyday. I'm not sure why or when, but it just happened. I know he doesn't hook up with girls since the days I'm not with him, we talk on the phone or text. The thing is, after being really good friends with him, I started liking him about two month ago. I don't know why, I've always suspected he is gay, but never really liked him. Now when I'm not with him, I'm always thinking about him. The thing is when I spend time with other friends, he is calling me up or texting me to get together. We mostly just hang out or smoke up together, no weird stuff. I've noticed how sometimes I tease him about never hooking up with girls and he gets really nervous and doesn't answer. There was even this one time when we were hanging out with my brother and his girlfriend, and she called up two girls so they would hook up with my friend and I. When they got there, he didn't even talk, he was just there being silent. At one point I had to tell him to talk to them, but nothing happened. Recently I found condoms beside his bed and in his car, which is really bothering me since I'm 100% sure he doesn't hook up with girls.

This is why I feel so sure about this one. My other crushes on straight friends I ignored since I knew they were straight, and I never insisted, but with this friend the clues are so obvious! I don't want to get into a gay relationship, but I think I really like him because we have a lot of things in common, we think really alike, and since we spend so much time together, what the heck. We make each other laugh a lot, and I actually enjoy spending time with him. Although I started to spend a lot of time with him last semester, I would still hang out a lot with all my friends, and he would always hit me up to hangout. This semester I've basically just spent time with him. In Christmas vacations he even texted me, not saying how he missed me or whatever, but how he wanted for school to start so we could hang out. He is very careful how he says things. We never talk about gay stuff, or behave gay in anyway, but just from the way he acts you can notice. We never have awkward gay moments. This semester I went on a school trip for a week, and he knew when I was getting back, but he texted me twice asking me when I was coming back, even thought he knew. Even my sister in law told me the other day how she thinks he es gay just because of the way he walks. I once had the chance (and felt really bad about it) to go thru his phone, and noticed how he doesn't have calls or texts with any girls in his phone, NONE! Even his facebook messages were all guys (not hitting on guys, just normal pal talk), which makes me think he is just very carefully and deeply in the closet as me. A lot of times I'm on my phone facebooking or whatever and when I look at him he is staring at me, and when he notices he looks away panicked. Most recently, another very awkward moment when we were smoking up, we were just talking, he went and laid back down in his bed, opened up his legs and was straight at me between right his legs while I spoke for a while (I hope you can picture this because I felt I needed to make a move but it was so weird, I got really hard but got so nervous).

So basically the feeling is mutual, when I don't call him, he calls me. Even the days I have to ignore him because I have a big test, I tell him: ok, I'll be done this day at this time, and he calls me up exactly at the same time I told him! Weird right? The other friends I liked never gave me clues like this. I wouldn't even rush to the sex part if the feeling was mutual, I just feel I need to be with him every day. I just think it's weird how we spend so much of our time together.

So I just want a good peace of advice to finding out if he likes guys or whatever, without having to come out to him. Coming out to him is not an option since I've never come out anyone and still don't feel ready. I do want to move on since I hate feeling this way and not being able to tell him. I don't to ignore him because that wouldn't be fair to him, and I don't want to come out to him because if he isn't into guys, that would make things awkward and I don't want that to happen. I just want to make sure before I make my move. Do you guys think he could maybe be asexual? I don't think so because why would he be posing with the condoms?? Maybe he is scared? I don't think that starting to touch him in a playful way would be good idea also since neither of us act that way, so that would be very awkward, for any of us. I also know that the fact that he doesn't hook up with girls doesn't mean he is gay, but believe me, where I'm from, it does. I also think I need to point out that my friend is not socially awkward or shy. What do you guys think? What approach or test could I use on him? And believe I do want to test him and move forward but not so severe as coming out to him. And sorry for the essay haha! I felt I needed to detail everything. THANKS!
