Turning a breach baby

Je
Hi all. I'm almost 27 weeks pregnant, and my son is acting just like his mama did in the womb - sitting with his feet crossed, all the way up in the air, and butt down (frank breach). I realize that he still has time to turn, but since I did the same thing when I was in the womb and didn't turn, I have some concern that he won't. 
My question is - have any of you ever had a doctor attempt to turn your baby head down for a vaginal delivery at the end of your pregnancy? What was that experience like? Were you able to refuse it and just ask for a cesarean? I have major reservations on turning a baby. 
Thank you!
