training w/ women
Hmm. The question of whether or not you train differently w/ a woman as opposed to a man necessarily pertains to each person involved. Personally I don't think there's much difference between how 2 guys train together and how 2 ladies train together. But when it's a guy and a lady... there we run into murky waters. I figure it depends on each person's point of view, and I am particularly in agreement with those who have said that you have to tailor your technique to uke's height, weight and ability. It's been said before, but it bears repeating, you don't koshi a 300lb gorilla the same way you koshi a dainty 100lb lady.
Having said that, I find it difficult to train w/ women because 1) I am a short guy (about 5'9) so I'm more or less their height and 2) I'm fairly new in Aikido (I've been training for about 6 months), so I will come right out and say it: I am afraid of accidentaly grabbing (in the midst of a tecnique, never on purpose, mind you)a girl's... umm, sensitive parts!
