The reason why some people say that homosexuality is influenced by culture is because Queer theorists are trying to include a bunch of different unconnected phenomenon together as one phenomenon (homosexuality).

To explain the differences between the phenomenon, they make the assertion that there are different types of homosexualites that exist in different societies. That these differences are caused by culture as they believe it massively shapes sexuality.

Numerous researchers studying the social construction of same-sex relationships have suggested that the concept of homosexuality would best be rendered as “homosexualities.” They document that same-sex relations have been and continue to be organised in distinctly categorical ways by different societies in different eras.

These variations are grouped by cultural anthropologist Stephen O. Murray into three separate modes of association:

Egalitarian, features two partners with no relevance to age. Additionally, both play the same socially-accepted sex role as heterosexuals of their own sex. This is exemplified by relationships currently prevalent in western society between partners of similar age and gender. Gender structured features each partner playing a different gender role. This is exemplified by traditional relations between men in the Mediterranean Basin, the Middle East and Central and South Asia, as well as two-spirit or shamanic gender-changing practices seen in native societies. Albania also has a similar practice where a woman may choose to be an “Albanian Virgin” and be given all the rights and entitlements of a man. In North America, this is best represented by the butch/femme practice. See Two-Spirit, and Hijra. Age structured features partners of different ages, usually one adolescent and the other adult. This is exemplified by pederasty among the Classical Greeks or those engaged in by novice samurai with more experienced warriors; southern Chinese boy-marriage rites; and ongoing Central Asian and Middle Eastern practices.
