When one is attracted (and aroused) by people of the same sex as them but this act is not perceived as homosexual
Homophobia is fueled by heterosexuals who exaggerate the gender norms assigned by our society to validate their sexuality. Paradoxically, heterosexuals have found a way for homoeroticism to be socially acceptable while still placing negative emphasis on homophobia. By developing techniques to normalize heterosexuality and “other” homosexuality, the dominant group continues to mistreat and alienate those who are different from them. Homophobia targets marginalized groups that ultimately reproduces sexism, racism, and classism.
Women often experience homoeroticism when they look at Sports Illustrated swimsuit models and think that they look sexy.
