PAP smears mostly screen for abnormal cells that could turn into cancer. While HPV is a sexually transmitted disease that certain strains can cause cancer, sometimes cancer can spontaneously occur. No sex doesn't automatically mean you have no risks, so I would strongly suggest having a discussion with your medical provider about it. Based on your family history, you may not need one at all, but one may be suggested just to make sure everything is normal.

I don't have any sources to suggest, but you could probably search on pubmed.gov for articles or abstracts related to this.
