A/N: Here's another of @Pixie_Otaku's requests. Tony's point of view.

Tony, I'm transgender.

The words left Peter's lips and he ducked his head and retreated out of my lab quickly, nervous as all hell.

"Ah. He's trans. He was wearing a binder, so that means he's a man that's trying to get past his feminine body. I'm gonna surprise him. With what though? A new binder set? Maybe I'll hand make them..." I mused to myself before starting to research.

I found out that transmen receive testosterone through shots, normally administered to themselves by themselves and wear binders until they can get top surgery. Top surgery leaves...scars...under the pecs...

Steve and Bucky are also trans and those shots are his T-shots?

I have to have a word with Steve and Bucky. Maybe later. For now, I'm going to continue my investigation of Peter's binding habits since you're only supposed to bind eight hours at a time.

"FRIDAY?" I asked.

"Yes, boss?"

"How long does Peter have a binder on at a time?" I asked the AI.

"Sometimes days at a time, even going out to fight and exercise in a binder."

I sighed, grinding the palms of my hands into my eyes out of tired frustration. "Thank you, FRIDAY." I huffed, slightly upset at Peter's habits as I pulled up more research about binders.

I ended up learning how to sew(which no, I did not know until now) and making binders and testing binders over and over again with myself(I had some fake boobs that I made to replicate the feeling of having boobs and now I have them for more than just challenges on the Internet) until I got it right.

I asked Nat to get Peter's chest measurements when he had his binder off, not leaving an explanation.

Nat came back with his measurements, handing them off to DUM-E as an acknowledgement that I was busy researching the best fabrics for binders and the best way to put them together some more after Bruce pointed out that there were better ways to sew binders together.

"Could you get Vision and Wanda in here for me, FRI?" I asked.

"Yes, boss."

A few minutes later as I struggled to pick out fabrics for Peter's binder set, Wanda came into the room with Vision, both looking confused.

"What did you call us here for, Mr Stark?" Vision asked politely.

"I need help with picking out fabric for three different binders that I'm going to make for Peter. Are you up for a sewing project?"

*several hours later*

"I have now missed dinner, but I don't care." I muttered, making the finishing touches on the gift bag before walking up to Peter's door and knocking on it.

Peter answered, wearing a huge black hoodie and a sports bra over a pair of men's basketball shorts.

"Hi, Pete. I have a little something for you..." I said softly, holding the bag out to him. Peter took it, confusion written all over his face. He opened the bag, dumping the contents onto the bed.

"Mr Stark, you made these for me?" He asked, tearing up.

"Yeah, kid, I did. Do you like them?" I asked, letting him envelope me in a hug, because he was three inches taller than me.

"Yes, Mr Stark, I love them, thank you so much, Mr Stark!" He exclaimed, putting me down and apologizing profusely for picking me up. I shrugged it off, laughing softly and assuring him that it was fine.

"Alright, kid, you can try them on, but if you fall asleep with one on, FRIDAY is supposed to yell at you. Don't make her do that." I said, walking back out of his room on my way to hunt Steve and Bucky down to give them the scolding of their lives for not telling me.
