I read somewhere that Danse develops similar feelings in the gay community. I am totally sure that I am straight but Danse is my favorite companion so far in the game, I have met the others but for one reason or the other I don't like to have them much time around except for Cait. And it kinda worries me that I might be gay, yeah I know that if you are gay you are supose to be proud and all that crap, but I am sure that if I ever felt like I were gay I would already know.
But at least let me explain to you why I prefer Danse.
I never cared bout Mcgready to get her as companion, never took Preston so idk how good or bad he is, I only know that he's uninsteresting and I don't like to talk to him much because of his quests, and I havent met Curie and the other dude.
Piper: I like her personality sorta, but her quest gives her available to you too quick, I can't see myself traveling around with Piper and feel safe, she's just a [censored] journalist, how can I even expect her to survive or defend herselv when she travels with me? I cant help but feel worried that she will get killed and [censored] by some raiders. I don't even think she ever killed anyone in her life before meeting me. Yeah I know companions in the game are immortal killing machines, but I am talking about her character, she doesn't look like that, and she's handed to you for no reason as a follower, doesn't she need to work? You would expect a journalist to be very busy.
Dogmeat: A damn dog that ruins my plans more often than not, plus he's a dog, do you seriously except a dog to save you from an army of super mutants? you even hear conversations of them talking about eating dogs, plus dogmeat animations when he's down make him look like he's suffering more than any other companion you will meet, and those sounds he make. I doubt it would be possible to realistically sneak around with that dog following you.
Codsworth: Smart and obedient, plus he's a robot so you won't care if he gets attacked or not, he's like a weapon with personality that talks to you and says your name. But he's weak later.
Strong: Better companion than the rest, but realistically who would trust to be around strong? he also complains a lot, I would never take him with me without fearing he would try to eat me if he becomes crazy at some point or if I do something that bothers him which already happens all the time. So [censored] him.
Cait: A junkie raider that probably had six with every guy, girl, and living thing around for jet. She's also bad in the head, and extremely dangerous, she have probably killed more people than you ever will, she has a huge distrust and grudge on mankind. At this point she's not even a human being, I've seen robots in the game more human and relatable than her. She's atractive yeah, but if I ever saw myself in a situation when I had to take her with me I would just ask her to go somewhere else out of fear that she would kill me when she's on drugs. I bet most people wouldn't even care about her if instead of an atractive girl she was some old fat guy with the same personality and past. And the fact that she have probably experienced every sixual fetish in a world already twisted, is a huge turn off for me. She's worse than a filthy [censored] in that aspect. No way to develop feelings for someone like that.
Nick: He's reliable, smart, careful, he's been in some battles, and you won't feel bad if you see him getting hurt because he's just a robot. But he's useless, I don't see Nick taking out a mirelurk queen by himself, he looks so weak, weaker than piper, he looks like some old man with cancer, I would only take him with me if I have to figure out stuff, like a password and [censored], but realistically I wouldn't even try to bother him and distract him because he's supose to be working just like piper.
Danse: Now we come to the last option, Danse, he's smart, loyal, strong, he's been through some serious [censored] but always kept his head cold, unlike Nick he's never been captured, you don't care if he takes damage because he's always wearing his glorious Power Armor, he even survived a Spaceship Rocket Ignition!, you can definitely trust him, he never ever lies, he's in the best faction in the game, unlike the other followers I see Danse entering a Super Mutant building alone and come out alive unscratched. And let's not forget how skilled he is to dissapear completly to the point the whole prydwen was unable to find him. He never tries to hurt you not even in his last moments, and he kept his loyalty and ideals to the point he was willing to die for them. Danse has everything, and his story and quests are much more interesting than the rest of the companions.
He affected my first playthrough to the point I never took another follower with me on my first char. That's why I think he's the best but I have a lot of valid reasons to say for sure that it's not a sixual attachment.
