Which term is used for a typically heterosexual man who sometimes wears clothing associated with women?

The term that refers to a typically heterosexual man who sometimes wears clothing associated with women is "cross-dresser." This label describes individuals who enjoy dressing in clothing traditionally attributed to the opposite gender, but it does not necessarily imply any change in their gender identity or sexual orientation. Cross-dressing can be seen as a form of expression rather than a reflection of one's identity as transgender, which involves a disconnect between one's gender identity and their biological sex.

In contrast, the other terms provided refer to different concepts. Transgender individuals have a gender identity that does not align with their sex assigned at birth, which is not the same as cross-dressing. Lesbian refers specifically to women who are attracted to other women, making it unrelated to the context of a heterosexual man wearing women's clothing. Heterosexual simply describes someone who is attracted to members of the opposite sex and does not encompass any behavior related to clothing choices or gender expression. Thus, "cross-dresser" most accurately captures the specific behavior and context described in the question.
