Enough with the big brain think about stuff bullshit. This is the kinda thing where you're supposed to read deep into it. I completely know I'm unreasonable, but they ain't gay. NOT ONE BIT. They explored but thats it. Just a little thing they tested out. They had bad previous relationships because relationships to them are easily broken and seems to be quite replaceable. Sooner or later their gonna have a whole fiasco, going crazy over some man and destroy their friendship. Go to the man's place, conquer a fear they both have, then move back together. It's gonna be this crazy loop and they won't quit because they are just plain old crazy people. This ain't some philosophical thing, just a manga about bad friends.
