Author's Note: Written for my best friend's birthday. First time writing this pairing, well, enjoy!

Tony walked into Steve's room, and found Captain America sat on the end of the bed, naked, with his hand wrapped around his hard cock. "Tony!" he gasped and froze.

"Impressive," he complimented.

"Tony!" he scolded, attempting to cover himself with his hands.

With a laugh, Tony turned. "I'm not looking," he promised, "if you want to cover up. Though, there's no need to on my account."

"Tony," he groaned over the rustle of material. "You can look," he stated.

The brunet turned and saw Steve had put on a pair of sweatpants. "Sure you don't want to take care of that?" he asked with a pointed look at Steve's tent.

"Is there a reason you're here?" the blonde demanded.

"Have you used it yet?"

"Used what?" he asked with a huff.

"The toy," he replied, causing the blonde to still. "No, I don't monitor your shopping habits, but I noticed the company on the package, and I know what they make. So…?"

Steve's face flamed. "Tony-"

"Did you read the package I gave you?" he demanded.

"I did," he sighed.

"So you know it's not unnatural to be part of the LGBT+ community, and widely accepted."

"Not everyone does," the blonde spoke softly.

"Eh, there's people who think the Nazi's were right," Tony spoke, waving it away, "so we can ignore the minority on this one. So it's fine if you're something other than straight, though I suppose you could have bought a Fleshlight, but I figure you wouldn't want-"

"A vibrator," he interrupted, "all right? I bought a vibrator."

"Was that so hard?" Tony asked with a grin.

He gave the brunet a look. "Did you have to do the LGBT talk?"

"LGBT+," he corrected.

"Plus?"

"LGBTTQQIAAP," he listed. "Did I miss anything Jarvis?"

"It depends upon which variation you go by, Sir."

"You're making that up," Steve spoke.

Tony shook his head. "Nope. Well, there are dozens of variations, so people tend to go by either LGBT+, or even LGBTQ+, but the former is more common."

"What do they all even stand for?"

"Lesbian, Gay, Bisexual, Transgender, Transsexual, Queer, Questioning, Intersex, Asexual, Ally, Pansexual," he listed without pause.

Steve blinked. "I don't know where to start."

Tony leant against Steve's desk. "Okay, you get the first four, right?"

He sighed and rubbed a hand over his face. "I can't believe I'm having this conversation, but yeah. And I even know the difference between Transgender and Transsexual. But wasn't 'queer' an insult?"

"It was," he admitted. "But the LGBT+ community is good at taking a derogatory term and making it their own. Embrace an insult, and it loses its power. But you get its meaning?"

"I can google it later if I need to."

Tony grinned. "I've finally heard you say it!" he said, overjoyed.

Steve shook his head, expression filled with fond exasperation. "What does Asexual mean?"

"Someone who feels little or no sexual attraction. They might have no desire whatsoever for sex, or they might like to participate in oral, or they might like make-out sessions but no more. It's down to each individual, the same as anything else. Make sense?"

The blonde nodded. "And Ally?"

"The same definition as you think. A straight person who supports those with the lifestyle, that'll stand against those that oppose it."

"'Pan' means 'everything', doesn't it?"

"Yep, they somethings call themselves 'gender-blind'."

"You sound like a dictionary. You haven't got Jarvis feeding you the answers, have you?" he asked suspiciously.

"No…but I did google exact definitions, just to make sure I got more than the gist. Basically, whoever you might be attracted to, or not, there's a designation. Although, just to be clear, an adult being attracted to a child is still not accepted."

"Good."

"Yeah," he agreed. His eyes strayed to the box on Steve's beside table. "You know how to use it?"

Steve blushed. "I can figure it out."

"Want a masterclass on sexual toys?"

"I thought you were a womaniser."

Tony grinned. "I've been with guys before, it's just rarer," he stated with a shrug. "And yes," he said with a sigh, "I was safe, and get regular testing."

Steve chuckled, then his expression turned resigned. "You're not going to let this go, are you?"

"Hey, if you really find this uncomfortable, I'll drop it, and recommend sites to check instead. And I realise you can heal a lot quicker than the average person, but I don't want you to hurt yourself. I won't even use yours, I'll demonstrate with my own toys."

"Okay," he sighed.

Tony grinned and dashed from the room to retrieve his box of toys.

Tony blew out a breath as he pushed the last few inches of the dildo inside himself. "Are you sure you were prepared for that?" Steve asked in concern.

"I know my limits," he assured. "And I wouldn't recommend you being this quick without more prep," he added.

"I was paying attention." Conflicting emotions flitted across his face.

"Steve," the brunet said slowly, voice slightly chiding.

"You said you get tested regularly?" Tony hummed agreeingly. "So you're clean?"

"What are you asking?" the brunet asked with a grin.

"Forget it," he said with a blush. "You're with Pepper and–"

"I'm not with Pepper," he stated. Steve blinked. "We thought about it for a while, but we wouldn't work that way. So…?" he prompted.

"Would you…" he trailed off, words dying as he met the genius' eyes.

Tony sighed. "I'm assuming, based on our queries, you're trying to ask for sex, with me," he remarked. "In case it wasn't clear," he said with firm eye contact, "I wouldn't be in this position, if I didn't want that." Steve blew out a relieved breath. "While I realise your upbringing makes this difficult to talk about, I need some clue about what you want. Do you want to go slow, start with hand jobs, maybe oral?"

"Honestly?" Tony nodded, expression encouraging. "I want to replace that dildo," he said in a rush.

Tony shivered. "Sounds good," he breathed. "But first," he said with a predatory grin. He wrapped his hand around the back of Steve's neck and tugged him into a heated, possessive kiss the blonde eagerly returned. He pulled back, panting hard. "For as long as we do this, you are mine, Steve Rogers," he purred possessively. "And I'm yours."

"Sounds good."
