yes, I can see how this would be a problem. I always WANTED to be able to sit on my seat and have my foot on the ground. Wah!
Can you scooter your bike with your butt on the seat? It might be a way to get used to scootering. You also might try sitting on the bar. Uncomfortable, but might help to learn scooter that way. Third idea might be to try starting with your other foot first and retrain your body and mind for the entire process.
Good luck.
