Is it disgusting to share a lollipop with a girl? Isn't it the same with sharing a drink or bitting of the same sandwhich?

I had a lollipop and this girl asked me if I have one more. I said no. She was then licking her lips. So I give her mine but I was joking around. She actually takes it and sucks on it for a while then gives it back.
I actually don't care I am comfortable with the person and I know she's "safe". Question to you: would that be considered disgusting? Isn't the same with sharing the same drink or food?
