@Mynona I definitely agree theres much more info about human sexuality that science havent been able to uncover so far. I'm also certain that the environment and culture play a role. It is possible the cultural environment play a bigger role than they credit it for but there are certain evidences from these studies that you can't really argue against. The FBOE effect for example has been replicated cross culturally several times. We dont know exactly what causes it but we know something happens while a male baby is inside his mother's womb that increases the chance this male fetus turns out a homosexual later on the more older brothers he has. They have accounted for environmental influence, they tested this with adopted brothers and the effect was only present among biological brothers
