Is Squamous HPV Contagious?

My sister knows she has HPV but hasnt been tested thoroughly yet. She will be soon. She is very promiscuous and I am worried that perhaps it can be contagious to people like me if I were to drink after her or something. I'm wondering if anyone has any information or if I'm being paranoid as I know very little about her type of HPV, which is squamous apparently, and I need help. Thank you.
