Heterosexuality
Heterosexuality refers to any attraction towards the opposite sex, whether expressed or not. Female Boylovers and Male Girllovers are among the group known as heterosexuals, as they express a preference towards members of the same sex.
On the other hand, heteronormativity refers to the set of values by which heterosexuality is ascribed status as the only valid form of sexuality. Accompanying prejudices against age-discrepant relationships are often so strong that heterosexual pedophilia and ephebophilia are denied status as valid heterosexual forms.
A derogatory or humorous boylover term for a heterosexual is cement-headed straight clown, or CHSC.
