Steve had come from a time where men liked women, and vice versa. So, when he woke up from the ice seventy years later to find that gay marriage was legal in a lot of the states, he was shocked. He really tried to be open minded, but it was just strange seeing men with other men and women with other women. Back in his day, anyone that liked thee same gender would be labeled "confused" and sent to get help with the church. Steve never had a problem with being gay, though. Well, at least not until he moved into the Avengers Tower.
Tony Stark, son of the late, great Howard, was a complete ass. Steve didn't understand how someone like Howard could make someone as bad as Tony. Tony was a drunk. He was arrogant, self obsessed, didn't play well with others. Steve couldn't stand him. But, he had moved into the Tower anyways. For the team. Luckily, he didn't see too much of Tony. They all had their separate floors. Then there was the common floor, which had a kitchen, living room, dining room, and game room. So, he didn't see any of the Avengers more that he had to, which was fine with him.
Then Steve's motorcycle broke. Someone had smashed it up. Steve was livid. But, Tony, being the mechanical genius he is, offered to fix it. Steve accepted. He didn't really want Tony helping, but he decided to let him fix it anyways. That way he wouldn't have to go out searching for a place to fix it.
So the next day, Steve went down to Tony's lab to see how everything was going. What he saw was a grease-smudged Tony in a wife beater and jeans. It took a moment before Tony realized Steve was standing there, but when he finally noticed, he looked up with a smile and said "Hey, Capsicle!"
Steve just stared. He found the sight attractive. Which confused him. He didn't like men. He didn't like his dead friend's son. And he most certainly didn't like Tony Stark. When Steve didn't reply, Tony just said "So…your motorcycle. It's gunna be a little harder to fix that I thought." And then Tony launched into an explanation of why, but Steve didn't understand. He had never been good with things like this. So he just nodded and pretended to listen. "But it's lunch time. So I think I'll take a break for now. Wanna go get something to eat?" Tony asked.
"What?" Steve said, only hearing the last part.
"Me. You. Lunch? Tony said with a smirk. "Come on, it's lunch time. Let me go take a shower first and then we'll go get something. Meet you downstairs in twenty minutes."
And just like that, Tony was out the door before Steve could make up an excuse for not going to lunch with him.
Tony couldn't believe what he had just done. He asked Steve out to lunch. At first he was just offering food because he was hungry, but when Steve looked at him shocked and confused, he decided to play it up and make the guy uncomfortable. So he basically asked him on a date, then left before he could say no. Tony knew what a good guy Steve was, he knew Steve wouldn't just stand him up.
Tony laughed to himself as he picked out clean clothes. He had to dress nice for the Cap, right? So he picked out a tight v-neck shirt that showed off his muscles and some skinny jeans. As he was getting dress, he briefly wondered why he was dressing like this. Was he trying to impress Steve? Nah. He was just trying to make him feel comfortable. Or, at least that's what he told himself.
Tony told Steve he'd be ready in twenty minutes, so naturally, he showed up five minutes late. Steve was standing there like a lost puppy. It was the funniest thing Tony had seen in a while. At the sound of Tony's laughter, Steve looked up.
"So, what do you want?" Tony asked, walking towards the blonde. "Pizza? Subs? Shawarma? Chinese? Something fancy?"
Steve thought for a minute before saying "Chinese?"
"Sure thing, Grandpa." Tony replied "Off we go!" and he led him out to one of his many, many cars.
