Final answer:
A person's sexual orientation is their physical, mental, emotional, and sexual attraction to a particular sex, and it can be categorized as heterosexuality, homosexuality, bisexuality, or asexuality.
Step-by-step explanation:
A person's sexual orientation is their physical, mental, emotional, and sexual attraction to a particular sex. Sexual orientation is typically divided into four categories: heterosexuality (attracted to individuals of the other sex), homosexuality (attracted to individuals of the same sex), bisexuality (attracted to individuals of either sex), and asexuality (no attraction to either sex). Questions of gender and sexuality also intersect prominently within sports. The International Olympic Committee and other sports governing organizations have faced challenges in establishing criteria for competition that respect the complex nature of gender biology and psychology. The case of Caster Seymena during the 2016 Summer Olympics illustrates the difficulties in reconciling hormonal levels with gender classification in sport. There is no scientific consensus on the exact reasons for an individual's sexual orientation, but research has explored factors such as genetic, hormonal, developmental, social, and cultural influences.
