Human Sexuality

This comprehensive overview explores the complex interplay of gender, sex roles, and sexual orientation in human sexuality. It discusses how chromosomes (XX for female, XY for male) influence physical gender and development, while also examining exceptions such as androgen insensitivity and hermaphroditism. The role of hormones in the womb and the nature vs. nurture debate highlight how gender identity is formed early in life. Additionally, the discussion covers cultural expectations, androgyny, and the importance of defining sexuality beyond stereotypes, emphasizing behavior over labels.
