"Ah, but I'm being thoroughly distracted." Well, he was until Bucky started to complain about his hair. His hand slides away from Bucky in favor of trying to push it out of the way--

And then he pauses, brows furrowing and mouth twitching into a frown as he pieces together what Bucky is insinuating. He's used to relatively consequence free encounters with him. He's not used to worrying about-- pregnancies or anything else. Bucky may have successfully killed any sort of arousal for a moment with the thought of cramps or babies if this is permanent and thorough by any stretch of the imagination.

"Did you... buy anything?" He's rather certain he'd have noticed if Bucky brought condoms, but there's a slight possibility, isn't there?

"There isn't any way of knowing if I could-- if whatever happened left me capable of that, you know."
