Being bisexual is not something to be made light of. It can be extremely confusing and heart-breaking, and it might be difficult to deal with emotionally. A bisexual woman is not there for your erotic entertainment, so if you want to spend your time with a bisexual woman, get that out of your head — this is not what this relationship is about. If your girlfriend comes out of the closet, treat it the same as if she told you she’s a lesbian: with kindness and care. If she decides that she would like to experiment with you and others, good for you both. If not, don’t push it.
