We can see here that writing an essay about homosexuality and bisexuality, we have:
Homosexuality refers to romantic and sexual attraction between individuals of the same gender. People who identify as homosexual or gay (for males) or lesbian (for females) experience emotional, romantic, and physical attractions predominantly or exclusively towards individuals of their own gender.
Bisexuality refers to individuals who experience attraction, emotional connections, or romantic relationships with people of both their own gender and other genders. Bisexual individuals may experience varying degrees of attraction to different genders, and their experiences and identities are diverse and unique.
