Effeminacy

Effeminacy or male femininity^[1]^[2] is the embodiment of feminine traits in boys or men, particularly those considered untypical of men or masculinity.^[3] These traits include roles, stereotypes, behaviors, and appearances that are socially associated with girls and women. Throughout history, men considered effeminate have faced prejudice and discrimination. Gay men are often stereotyped as being effeminate, and vice versa. However, femininity, masculinity, and other forms of gender expression are independent of sexual orientation.
