Yes, let's talk about how Steve could have m/m sex in a homophobic culture, especially if he also (canonically) likes girls.

I'm thinking about the historical novel series set during WWI by Pat Barker--the Regeneration trilogy, that's it. The protagonist is bi, has sex with men. They just don't talk about it.

So I'm wondering if what could make Captain America slash seem plausible is if he has had sex with pals in the army but...I don't know. One story I liked had him have a crush on Tony's dad and also be aware that he was "queer" and really afraid of being found out.

What do you think would work?
