1) All I remember is the team was incredibly comfortable with each other. They would walk around shirtless, in just their underwear, etc. I think someone came into the tower and was shocked to discover this.
(Sorry this is so late) Found by ellid. The Photograph
2) Steve isn't the blushing virgin a lot of fics like to make him out to be. He learned a few things from the girls in the dancing line of the USO tour (not necessarily sexual in nature, though there might have been some), as well as from his time leading the Howling Commandos. The team is learning this over drinks or something.
I finally found it!!!! Gentle Heart Part of the "Muscle Mass" series. The list is found at the author's page
PS: Since the descriptions of the fics are kinda vague (and since they're of a theme I really like), if there are any recs you can make to a similar theme, toss them my way please.
Please and Thank-you!
