I don't know that there is a culture (other than some subcultures in the modern First World) who don't consider sex sacred, though certainly there's quite a gap between "Son, if you ever lust after another guy you're going to Hell!" and "Son, if you don't suck enough cock, you'll lose your vital energy!".
Not sure what you mean by "sacred". Almost everybody obsesses about it, positively or negatively. Is that sacredness?
