You can get HPV without sex too.

"HPV is most commonly spread during vaginal or anal sex. It also spreads through close skin-to-skin touching during sex"

This focuses on sex, but any virus that can be found on skin, also has a chance to be transmitted without sex just as well. Admittedly the chance here for HPV infection is much higher with regard to sex, but not non-zero otherwise. The HeLa cells also contain a HPV virus in the genome, though this was probably transmitted via sex:

"The cells are characterized to contain human papillomavirus 18 (HPV-18)"

HPV-18. I think HPV-18 may in general be more prevalent than HPV-16.
