Steve tries to give Tony space, he really does. He doesn't want to be the clingy boyfriend, no matter how undeniably clingy he is. He doesn't want Tony to think he's needy. Besides, backing off has worked so far, so as much as he might want to try otherwise, he leaves Tony alone, apart from the odd text, usually couched in a business question.

The selfie of Tony wearing his collar is the last thing Steve expects to get, but he can't deny the very physical reaction it gets from him. He thinks back to when he'd given it to Tony, when he'd straddled his abdomen and jerked off on his chest, come glistening everywhere, Tony blissed out and completely in tune with him. It's definitely a memory he's savored more than once, and he wonders if Tony feels the same way.

But Steve, being Steve, doesn't immediately go down the innuendo route, unlike any other person. Does it help you sleep? he asks instead.
