I have not. My bike is "basic black" with no decoration. Since I ride in full gear all the time, people really can't tell my gender at a glance.
It can be fun when they realize I'm a girl.
One day a couple of months ago, I stopped at a traffic light where I was first in line. A woman pushing a baby in a stroller, accompanied by a boy of perhaps 4 or 5, approached the crosswalk. I made eye contact, nodded, and signaled with my hand that they were safe to cross.
The little boy said, "Hello," as they went by, and I answered, "Hello!"
When they'd finished crossing the street, I heard the little boy say, with surprise in his voice, "Mama, that was a LADY on that black motorcycle!"
