With the Avengers finding out Steve is gay, his relationships would evolve. For instance, Sam Wilson would be extremely supportive. He and Steve already have a great friendship, and this would only add another layer to it. Steve's relationship with Bruce Banner might also change. Bruce, who often feels like an outcast himself, could relate to Steve on a different level. They might have more in - depth conversations about acceptance and self - identity. And Steve's connection with Rhodey could strengthen as Rhodey is a man of honor and would respect Steve no matter what. Overall, Steve's relationships with the Avengers would become more multifaceted and based on a deeper understanding of one another.
Well, it could potentially strengthen the bond within the Avengers. They are a family of sorts, and if Steve is gay, they would accept him wholeheartedly. They've faced all kinds of differences before, like Thor being an Asgardian. This would just be another aspect of Steve that they'd embrace, and it might even make them more united in the face of any external judgment.
Steve would probably be quite honest. He might just come clean and start sharing his experiences as a young man. He'd want the Avengers to understand that he's still the same person at his core.
Well, some of them might be really surprised. Tony, for example, would probably crack a lot of jokes about Steve being young. He might say things like 'Cap, you were this cute little thing?' Natasha, on the other hand, would be more observant and start thinking about how this new information could be used in future strategies. Thor would probably just laugh heartily and pat Steve on the back, saying something like 'Tis an interesting discovery, young Steve!'

The Avengers' reactions to finding out about Steve and Bucky in fanfiction would be diverse. Bruce might be more analytical and wonder why fans would write such things. Wanda could be empathetic and see it as a creative expression of the bond between Steve and Bucky. Vision, on the other hand, might try to understand the cultural significance of fanfiction in relation to the two heroes. Steve would likely need some time to get used to the idea that there are fictional stories out there about him and his best friend.
Thor would be quite confused at first. Fanfiction is not something from Asgard. But once he gets the gist, he might say something like 'This is a strange Midgardian custom, but if it shows the great friendship of Steve and Bucky, then it is not all bad.' Meanwhile, Tony would be all over Steve, making snarky comments and asking if he's finally going to admit to some hidden feelings for Bucky according to the fanfiction.
In a fanfic, when the Avengers find out Matt is blind, it could lead to a whole new dynamic within the group. They would start to see Matt in a different light. Some might underestimate him at first, but as they see him in action, they'd realize his blindness doesn't hold him back. His heightened senses would amaze them. For instance, his ability to 'hear' the layout of a room or sense an enemy's approach. This new knowledge would also make the Avengers more protective of Matt in dangerous situations, and they might even learn from him how to rely more on their other senses too.
Tony Stark would probably be both proud and a bit worried. Proud because Peter is this brilliant young mind who has managed to be a hero on his own, but worried because he's just a kid. He might start to hover over Peter more, offering him better tech and trying to mentor him more closely. Captain America would likely be very accepting. He sees the good in people and would be happy to have another brave soul on the team. He'd probably offer Peter some words of wisdom about using his powers responsibly. Thor might be a bit clueless at first. He doesn't quite understand the whole 'secret identity' thing as well as the others, but once he gets it, he'd be all for having Peter around. He might see Peter as a little warrior and be eager to train him in his own Asgardian ways.
