Final answer:
A homosexual is someone whose main interest is towards members of the same sex. This term falls under the larger category of sexual orientation, which also includes heterosexuality, bisexuality, and asexuality.
Step-by-step explanation:
A homosexual is a person whose primary erotic, psychological, emotional, and social interest is towards a member of his or her same sex. The term homosexuality defines the attraction to individuals of the same sex, and it is one of several categories of sexual orientation, which include heterosexuality (attraction to the opposite sex), bisexuality (attraction to both sexes), and asexuality (no sexual attraction to either sex).
Sexual orientation is a deep part of one's identity and encompasses a range of attractions beyond just physical, combining romantic and emotional elements as well. It is widely acknowledged that cultural norms and societal attitudes significantly influence how sexual practices and orientations are perceived and expressed.
