I was mistaken for a man yesterday

[shootingstar]

I kind of thought of it is a compliment but, after all of my trials and tribulations as a woman, I want to be recognized as female.

Yes, for your achievements?

Frankly, I really don't care what others think of me when I'm cycling.

and I look pretty flat because I'm small upstairs below my chin.

C'est la vie. there are worse things in life than have mistaken gender identity (except for the teenage track star athlete that we've heard about a few weeks ago).

back to the OP, remember, this was your son who probably has burned into his memory forever YOUR butt cheek. he's doing his best to process this HORRIBLE memory.
Perhaps a less jaded person would not think you looked like a man!
