Captain America did this kind of thing all the time.
Also, in the latter case, I'm pretty sure one of the results of the chemistry is that he really struggled to believe anyone could value him *except* for that. He wasn't a self-assured golden boy on the inside, he was a wounded bird who could still hop around as joyfully as anybody, but who spent a lot of time hiding that his wings were broken, performing for a crowd of people whose affection was conditional (or so it seemed to him) on his performance.
He and I never had sex, which I think is one reason why we appreciated each other so much. We both let each other just BE, without that expectation. (I definitely fell into the older-wiser-sister role with him, though, even though he's nearly a year older than I am.)
