Some people use this song to question Anna's sexuality, but I think that is taking the interpretation a little too literally. I believe that when Anna says, 'I'll Be Your Man' she is talking about taking on the role of a male in the relationship, ie, supporting her lover, being strong and protecting them. Rather than a sexuality thing, it seems to be a reversal of gender stereotypes.
