male sexual desire for female is healthy and should not be discouraged. for if females are removed from the equation (ie in prison, in priesthood, or by completely covering them up and making them walk around in bed sheets as if they are pretending to be ghosts on Halloween), the result is the same everywhere: that deviant and perverse sexual behavior will then start to emerge.
now this is completely different than homosexuality, which I believe is completely biological. we have a lot of scientific evidence to suggest this.
however, this does not make science a friend of the GLBT community, as this article demonstrates:
in fact, by refusing to admit that homosexuality is biological, the church is in fact allowing homosexuality to continue. whereas science, by recognizing homosexuality is in fact a condition caused by too much exposure of the wrong hormone in utero, we might head down toward a path of finding a treatment that may prevent future homosexuals.
