I'd like to point out that this issue is a rare annoyance for me..I have a good relationship with all the regular students of the dojo and we respect each other...but the annoyance comes from newbie's and is annoying enough for me to get a chip on my shoulder.
It's the south.. the good ol' boy chivalry gets annoying after awhile.
There are some boys that don't know me,(they are new), but they are fully aware that I'm a higher rank than them, so it is a little rude to assume I need "their instruction", and assume that I need "their" help taking ukemi, or the mat will some how hurt me. They don't treat other men like that; other men who are lower ranked than me...so after a while I'll have to assume it is them "trying to be nice to the girl".
I only get mad if I'm injured due to some one ignoring my wishes to say, let go of me when I fall. I tend to repeat myself by saying "I don't need help to the mat, you are going to injure me." And if I am injured, I'm obviously irritated.
Don't expect special treatment. I train with male students, I train as hard as them. MY only point really is that altering your teaching or training style for a woman is really an insult more than it is a help. And if the newbies annoying me stick around long enough they learn this fact...then everything is cool.
I expect special treatment. I'm tall and skinny. I'm inexperienced but have a high level of endurance. I'm male. I have a 7 year old in the class (during the family practice). I'm approaching middle age. My shoulders are flexible. My wrists are not. I can put my feet behind my head but can't touch my toes.
A good nage needs to treat me appropriately or the techniques won't work and/or they might injure me. A good teacher needs to consider these things while teaching me. Some of them they can perceive instantly. Some of them they can glean from putting me into categories. Some times these categories may mislead them but we can work through that.
Hopefully I treat others as special cases as well and I adapt to who they are and what they are doing.
