There is nothing to be embarrassed about. If you have a friend, family member, neighbor or coworker with a simple bike, explain why you can't ride just like you did to us complete strangers on the internet. Nobody here is putting you down and I'm sure they probably won't either. You would probably be surprised how quickly one of them can teach you in an empty parking lot. Good luck and I hope you come back and post soon how easy and fun it was for you.
