Doctors usually will not do a tubal on a patient if she is under 21-get this-without your parents signing for it-even if your married. I'm assuming your over 21, it may take a few doctor consult's to find one who is willing, and yes they will try to talk you out of it, but it's possible.

I had one when I was 26, after three children, and they still tried to talk me out of it. But I was persistant and I after they delivered the baby(via c-section) I popped my head up and asked just to make sure they were doing it.
