Mark - I don't think he'd have any shame, or it would happen by accident and he'd be embarrassed, but laugh it off
Jisung - He'd probably just forget where he was or why he shouldn't of it, and it would happen
Jaemin - Once he felt comfortable, he would do it
Jeno - If you were okay with it, he'd be able to
Renjun - Same as Jeno, but he would still feel a little awkward
Chenle - He wouldn't mean to do it early, but it might happen by accident, and he would be embarrassed
Haechan - He'd be too polite, and at least ask before it happened
