Bisexuality involves physical and romantic attraction to both males and females. Freud theorized that everyone has traces of bisexuality due to anatomical similarities in early development. Bisexuality has been viewed negatively with stereotypes of disease, inability to commit, and betrayal for leaving a same-sex partner for an opposite-sex one. However, human sexuality exists on a spectrum and people should have the freedom to choose partners without harming others or limiting their choices.
