Steve honestly didn't know how long he'd last, at this point. He'd heard other guys talk (hell, he'd heard Bucky talk) about what it was like to be with a dame, but he was pretty sure he wanted to last longer than that. The only sexual experience he had was with Rosie Palm and her five sisters, but he was pretty sure it was different when it was just you and your hand and your imagination, trying to reach climax. Energy and stamina weren't quite the same thing, when it came to sex, he was pretty sure.

When she wiggled in his lap, Steve bit back another groan, his hands tightening on her hips to keep her immobile. "Please!--don't do that." He huffed a little. "I can drive," he said, a little defensively. Then he admitted, "It'll either be really painful... or it'll help take the edge off." On long drives, he'd gotten hard just from the rumble of the engine, but it wasn't that far to his apartment, it might not be so bad.

....he could be wrong, though.
