Male Friendships (any genre)

I really love the friendship between Naruto and Sakuke! (Also, can people stop calling it "gay" any time two guys are close to each other? Homophobes are obviously much worse, but fujoshi who see every male relationship as gay can be pretty annoying as well)

This was once my favorite manga in the world... I really liked the friendship between Killua and Gon, although Gon as a character honestly isn't my favorite, and I think he treated Killua quite badly at times

NOT shounen ai - purely platonic

NOT shounen ai - purely familial

This one is beginning to piss me off. The subtext is just text at this point :(
Edit: I hate fujobait with a passion, and that's what this has become... Give me platonic friendships or give me BL, but do not give me gay crap disguised as "friendship" that is obviously meant to cater to fujos. You cannot tell me this fuck-ass manga is aimed at straight men. It's very possible to write a strong male relationship that isn't obvious fujobait, but this ain't it chief

The only actual shounen ai comic on this list so far...

NOT shounen ai - purely platonic

I really like sibling relationships, especially twins!
