I don't think a homosexual, as we understand them today; people who through no fault of there own, are attracted only To people of the same sex, existed in early biblical culture. It is very likely the followers of Mosses knew of same sex relations, and assumed, as many bigots today do, that the person engaging in such activity is a pervert, looking only for cheap sexual satisfaction, acting against his heterosexual norms. I don't think it was with in there scope of reference, that a person could have been created that way, it is likely that laws latter witten prohibiting homosexual sexual activity, were out of disdain for the "evil ways" of the Egyptians.
