What term describes an individual whose sexual desires are directed to both men and women?

The term that describes an individual whose sexual desires are directed to both men and women is "bisexual." This definition encompasses the attraction to individuals of both genders, which distinguishes bisexuality from other sexual orientations.

Lesbian refers specifically to women who are attracted to other women, while homosexual generally refers to individuals attracted to members of the same sex, regardless of whether they are male or female. Transvestite references a person who dresses in clothing typically associated with the opposite gender for various reasons, including expression or performance, and does not inherently pertain to sexual orientation. Thus, the selection of the term "bisexual" is accurate as it precisely describes the described sexual preferences.
