A lot of what's being described here strikes me as bro culture, not "hetrosexual culture," if there is such a thing.
Frankly, I don't think there's such a thing, because I don't think you can, for instance, say there's such a thing as "homosexual culture" either for instance. Not without projecting or getting into stereotypes. If you're going to lump millions, or even billions of people together because of their sexuality, then, well, keep in mind that some people have done that before (and do), and generally not with good intentions.
