Yes, you're right. But am I thinking too much as a blue belt? I mean, I'm not a good uke yet, not a good nage either. Can't really control myself must of the time. Maybe I should be quiet and practice. But I will try to talk to the new girls and the new guy what they want. I hope I'll won't waste their time practicing with me...
As newbies they may not really be able to really articulate goals. But it is certainly within the norm for uke to ask if the last attack was too fast, too slow, too hard, too soft or just right
Once your partner has some experience, a very good question to ask is: would you like feedback on how it feels, or do you just want to keep going and work on figuring it out as you go?
