It is, Yoongi realizes a touch too late, probably a question he should have saved for later. There's no reason sex has to be something solemn, but it's still serious. At least, even when they're playful about it, he takes it seriously. He just wants to make sure they're both comfortable with what they do. Talking about it like this makes it hard to gauge if that's the case.

Squeezing Jungkook's hand, he steps off to the side, turning so he can look at him, even if Jungkook isn't returning his gaze. "Breathplay?" he echoes, keeping his voice low. "Like... controlling how someone breathes?" He's watched his share of porn, but that's not something he's really explored. It sounds dangerous, frankly, and he's not sure how to approach that — which, he thinks, just means he's going to have to do some research. The last thing he wants to do is take anything too far and hurt Jungkook, but there's little he'd be opposed to at least trying if it made Jungkook happy. "I can learn. That. And ropes. If that's something you want to try."
