Almost all other animals only have sex seasonally. Humans (and bonobos) are the only species who have sex whenever they want because of *social* cooperative survival strategies.
This biological revolution entails fluidity in sexual orientation. Indeed, bonobos are fully bisexual.
Human sexuality is a phenomenon that scientists are still investigating. It is fascinating.
In situations where the opposite sex is unavailable, it would be impossible for bisexuality to occur, unless humans were biologically bisexual.
I don't regard people in extreme situations like prison as gay or bi sexual if they take a lover. Its whats available not what they have a choice of. I know one women who is more or less hetrosexual but takes women lovers instead due to what happened to her with an ex boyfriend. She craves someone to care for her but its not really her 1st choice but she takes whats available for her due to her back ground. She is to scared of the males and its a fling with the girls. Extreme situation not gonna stick a label on that.
