Off the top of my head, there's that moment in the Fateful Encounter omake where Cana's complaining about not having a boyfriend because "with the men gone for a while, my body's become a bit lonely". She then proceeds to sort of tease Lucy when Lucy reveals she's never had a boyfriend. Not sure how close that is to the original Japanese, but it was pretty hinting (for me at least) about her having had past relationships.
