I have been considering getting an IUC and have never given birth. When I talked to my gyno, she explained why it's generally recommended for women who have had children - it's easier to insert (and therefore less painful) and it's less likely to come out. In someone like you or me, your cervix is not as responsive to that stretch and may push it out. The chances of that happening are low, but higher than if you had given birth before. Unless he or she has some good reason not to give it to you, there really shouldn't be a problem with getting an IUC. I am a college student and the gynos here say they do TONS of IUC insertions each semester, and I guarentee you that most of these girls are not mothers.

Good luck!
