Cana has been sometimes lonely so she acts unladylike she drinks cerveza too much but if she is a lesbian no boy can fall in amor with her and also i wonder if cana is lesbian it will be ok to gildarts?
Yes, she is at least bi. but i think she is más lesbian over the years. in the episode 108 min 17:05 she kinda stutter before asking Lucy his companion to go buscar in the forest. in addition to other scenes where she "get a taste" (sic) of Lucy's boobs
i can't really say that she's a lesbian but i can speculate that she's bisexual as we can see during the new episodes (after the 1 año absence especially). that o she's very comfortable around lucy and openly flirts just because it's her personality. either way, she's still a pretty cool character.
