I heard around that (generally) if a man's hand falls asleep while cuddling, he's likely to not do anything about it. Not sure why, I just heard that. I think maybe that is in part because many men want/are expected to act tough like 24/7, 365 days a year, and show no weakness.
Do you (men, or women) have a difficulty with letting your cuddle partner know of your physical discomfort?
With my limited cuddle experience, I'd say I've little to no issue voicing physical discomfort. Maybe I'll toughen up for a minute or two, though I'd voice it, or just change position. Sometimes I also notice when someone is acting tough, hence I call them out on it: in a calm and collected manner of course. Or I keep going with whatever for a bit more before I suggest a break and whatnot.
