Apparently the HPV virus is spread from sexual contact-this doesn't just mean penetrative sex, so as a lesbian, you are still at risk. In all honesty, I would reccomend getting the jabs- I think a little needle fear is worth getting rid of the risk of cervical cancer, but obviously it's up to you. Also, while you're a virgin and not on the pill now, in a few years your circumstances might change.
I do have a massive leaflet about it kicking around somewhere from school, so if you do have any more questions, lemme know and I'll see what it says!
