Listen he never would have said that to anyone but a heteronormative dude like himself (okay) or you know, Cap. But he wasn't thinking about him being bi when he said it. Because he doesn't think about him being bi ever (gross!) - yeah no, that was bad. Pepper probably would have hit him bad.

"Bad joke. Like. Whole new level of terrible." He pulls away a little to grimace. This is his apology face, you can keep doing that back rub thing. Sighs. He ruins everything. "...What did make you realize that though? Uh. I mean. If you... want to answer." Is that better???? Christ.
