So interesting thing has happened. Not really with me though. Franks little brother (he is like 13) uses my computer on occasion when he comes over with frank. I was told by john  there were some interesting searches on the guest account. So I looked at them. Turns out he was trying to look at porn. At that trying to find miley Cyrus nude pictures and zac efron nude pictures. So I said something to frank. I guess frank found other searches on their computer with naked guys being the topic. So I've decided to talk to him about what I've found and not say anything about what frank found. And I don't think I'll point out specifically what I found but just say I know what he was looking at and he should stop if he can't cover it up... That would be terrible for him if that was found by his parents. 
But I have a theory. I guess it was found out franks brother and cousin(a guy) had sex in the past. Franks cousin is maybe a year older than his brother. And I know it had to be over two years ago. Supposedly they actually got penetration. Which is confusing me a lot. Franks brother couldn't have gotten hard at that age... I know because I've had to explain it to him because frank won't. And I told him about masturbation... If he didn't know about jacking off how could he know anal sex? But my theory is he is curious about it all. I know because of my sexual experiences from when I was younger made (and continues to make) me curious.
But... I'm looking for what I should say to him. I think I'll just leave it at don't look at any porn on my computer or any other computer  if you can't cover it up. It will only cause problems. I will tell him I'll keep it to myself. I really just feel like sharing my feelings about sexuality but I can't. It will be misinterpreted by him since he is so young. 
Frank just kept saying that all this just makes him wonder. Which it does me too. But I explained why I thought he was probably just curious and that I went through it when I started thinking about the things I went through.
		
		
	 
Dude, I'm gonna say this because I see a lot of myself in you, and I say it with the utmost respect and love two dudes who have never met can muster: you are too freaking chatty with your guy. 
Nevermind the mental exhaustion 
I know you must be going through(it's showing in your posts) - that's your cross to bear, but if you're not careful, you could push your friend away. Others have the nail on the head when they said that your friend does not like talking about this stuff particularly his personal experiences. If he spoons you at night when you guys share a bed, 
don't bring it up and break it down with him the next day. Cause if you don't, pretty soon he's gonna stop shrugging it off and giving you noncomittal answers about how he may feel or think about it, and he's gonna suddenly want to sleep on the floor cause "it's better for his back" or he'll want to sleep on the sofa because the air is better or something, and then he's gonna start giving you reasons why he can't sleep over. Don't even bring it up as a joke or reference. Don't. 
Here's another bit of experience from my personal life: you are not as cleverly hidden as you think you are. Your friend is not as oblivious as you think he is. He knows exactly what you're up to. Not because you got this big honking sign saying your intentions, but because he is your best friend/brother. Who better to know than him? And honestly dude, your hints aren't exactly hidden or veiled. He knows. And he's choosing to overlook it. He's focusing on the friendship you guys have. 
I mean, he does show comfort levels with you, but the stuff he is uncomfortable with is probably the stuff that you pushed too hard on. At the end of the day man, he probably genuinely loves you, and he does NOT want to treat you like some sex whatever. What you guys have is so much deeper and important than fooling around. 
And on the subject of your "feelings" for him. It sounds like you are falling for or have fallen for him. It can slip up on ya. 
Oh, also, don't talk to his brother about the internet searches. The best thing is to say nothing, or if something just has to be said, then it should be left to his brother to say it. I mean everyone was 13 at one time and I personally would have been mortified if one of my brother's friends tried to have a conversation about that stuff - even in the pretense of giving advice. Wouldn't you? So, please for the love of God, stop talking! And I mean that nicely 
 
  
Dial it back. Let your friend do the talking/acting. You just react. 
And try to focus on your friendship please!
However, after all my negative-ness, his discomfort might come from him not being able to "control" himself around you 
 
I hope you're doing well dude
