thats true but theres also a possibility that this occurs beyond a biological level too. i recently saw a study which had results showing that the black community has the highest amount of homosexuality both gay and lesbian
Black Gays Make Up Largest Share Of LGBT Community, Survey Shows
the only explanation i could form was to link this to the amount of fatherlessness. other than that it doesnt really make sense why it would be higher. if homosexuality was genetic, it should be the same across the board - not higher here and lower there
on a personal level i notice this a lot with black women. a lot more black women are lesbian than other races of women. its seems like there are way more now too even than when i was say like middle school
there HAS to be a cultural element.
my best guess: the role of fathers as initiators or ambassadors if you will to masculinity
