What is the definition of the term "gay" as commonly used?

The term "gay" is commonly defined as referring specifically to men who are attracted to other men. This term encompasses not only a romantic or sexual attraction but also often includes a broader identification with the culture and community of individuals who share similar experiences. While the understanding of sexual orientation has evolved and expanded to encompass a variety of identities, the use of "gay" primarily highlights male same-sex attraction.

Other options describe different groups or identities: the first option refers to heterosexual men, the second option relates to a perspective on gender identity tied to biological sex, and the fourth option encompasses a broader spectrum of attractions, typically described as pansexuality or bisexuality. Thus, "gay" is distinctively connected to men attracted to men, making it the correct definition in this context.
