Hinky Flutter Kick

Hello on a rainy Sunday! Can anyone offer advice on whether and how to straighten out twisted legs in a flutter kick? They're fine when I swim flat in the water and when I kick on my left side, but I'm trying out the Total Immersion technique and find when I kick on my right side my legs kind of thrash around in the water, my top leg knee dips down and interferes with my lower leg so much that I'm not really doing a flutter kick anymore. sigh. I guess its a knock-kneed kick. If I swim LESS on my side it's less of a problem. And if I bend my knees a little more than recommended (but not too horribly much) its less of a problem. I'm devoting some time, as I begin my master's fitness swimming life, to improving my technique. But I want to be realistic--I don't want to spend months retraining my legs (they've apparently been moving this way for decades, who knew?) and sacrifice fitness/yardage/ and honestly, calories burned. thanks for any suggestions, I'll be working with a coach on Tuesday and can get some help with observing what's happening, too. :confused:
